Ford flex wont start DEFAULT

 

 

It can be very frustrating when a vehicle won&#;t start.  There are many different issues that can cause the problem.  This article is written with the assumption that you are looking for a way to get your Ford Flex started now, and is meant to provide you with practical advice to help aid in the diagnosis.

There are really two main ways that a vehicle will not start.  The first and most common is when it won&#;t turn over.  This just means that the engine doesn&#;t move when you turn the key.  The second way that your Flex won&#;t start is when the engine turns when you engage the starter, but it won&#;t fire and run on its own.  When the engine isn&#;t turning over at all, that&#;s a bit easier to diagnose than when it is cranking but not firing.  Just use the jump list below to move to your particular situation.

Ford Flex Won&#;t Start:  Not Cranking

There can be many reasons why your Flex won&#;t start.  But, there are less things to troubleshoot than if it were cranking but will not start.  Here are some of the most common issues that cause a vehicle to not crank:

 

1.  Battery Cables

While the battery cables are not necessarily the most likely issue to cause your Flex to not start, they are some of the easiest to diagnose.  You can take a look at the battery poles where the cables connect.  If there appears to be green or white corrosion all around it, cleaning them may help get you back on the road.

Here&#;s a good article from Napa on how to clean a battery terminal properly.

 

2.  Battery Charge

If your battery no longer has enough charge to turn the starter, your Flex will not start.  As a battery ages, it&#;s &#;cranking amps&#; decrease, leaving it with a diminished capacity for starting the vehicle.

When this happens, you&#;ll often hear the vehicle crank slowly, but not start. 

You can take your battery up to the local parts store, or even Wal-Mart, and have it tested to see if it is still holding a charge.

  • Battery is Dead&#;  If it&#;s dead, but charges back up and tests &#;good&#;, it would be time to check the battery terminals or have the alternator tested and see if it is properly charging the battery.
  • Battery is Charged&#;  If the battery is charged, then it would still be advisable to take a look at the battery cables and see if there is an issue with corrosion.  Otherwise, it may be the starter that you need to look at.

A bad alternator can cause your battery to lose enough charge to start your Flex.  It may have had enough energy to get you home, but when you go to start the vehicle, there&#;s not enough stored energy for the engine to turn over.

 

3.  Starter

The next thing to look at when your Flex isn&#;t starting would be the starter itself.  When the starter isn&#;t functioning, it is impossible to start the vehicle (unless it&#;s a manual, then you can pop start it).  

If you&#;ve determined that a fully charged battery without corroded cable is the culprit, then it&#;s time to question whether or not you need a new starter.  When a starter goes bad, they will usually not give you much warning first.  Also, if you are stuck somewhere and are trying to start your Flex, the old beat the starter with a hammer trick is not a wives tale.  It really can get that one last start out of it.

 

 

Ford Flex:  Engine Cranks → Won&#;t Start

There are a lot of issues that can cause your Flex to crank, but not start.  The engine needs air, fuel, and a spark in order to run.

It is highly likely that if the engine is cranking, but not starting that it has thrown an OBDII code.  It is definitely worth it to use an OBDII scanner to check and see if the engine has thrown any trouble codes.  It is highly likely that if your Flex won&#;t start that there will be codes.  These codes will tell you what the computer is saying is wrong with your engine.

By looking them up on this site, or just Googling them in general will lead you to a detailed diagnosis of that code.  Hopefully, once the code has been addressed your Flex&#;s engine will start again.

 

Ford Flex Won't Start Diagnosis

 

1.  Fuel Issues

If your Flex isn&#;t getting enough fuel, or any fuel at all, it may have a bad fuel filter, bad fuel pump, or bad fuel injectors.  Without the proper amount of fuel getting into the combustion chamber, the Flex will crank, but not start.

 

2.  Ignition Issues

One of the biggest issues that causes a vehicle to crank but not start is ignition issues.  When there is no spark, the engine will not start.  You&#;ll probably have a misfire related code such as P, P, etc&#;..

Ignition issues can be caused by many things, including bad spark plugs, bad coil packs, bad plug wires, computer issues, and more.

 

3.  Engine Timing

If the engine&#;s ability to fire the spark plug at the right time is called &#;timing&#;.  If the plugs are firing at the wrong time, or something has happened to cause the camshaft to no longer be in sync with the crankshaft, your Flex won&#;t start.

There will usually be OBDII codes associated with timing related problems, but not always.  P is a common camshaft position related code.  The crankshaft sensor can go bad as well.  When these sensors go bad, it can be impossible for your Flex to start.

 

4. Security

Most modern vehicles come with smart keys that have electronic protection built in.  This makes it more challenging for thieves to steal them.  There are occasions where this security system will cause the Flex to not start.  You&#;ll see a security warning when trying to crank the engine though.

 

5.  Other Issues

There are a lot of issues that can cause your Flex to not start.  That&#;s why it is so important to check everything.  Here&#;s a great diagnostic chart that covers many different variables.  

 

Conclusion:  Ford Flex Not Starting

There are many reasons that your Flex may not start.  Tracking them down can be downright challenging.  With enough time and patience, you can diagnose exactly what is wrong.  Good luck with the diagnosis.  If there is anything that you would like to add, please leave a comment below.  Thank you.

There are a number of issues that can go wrong with starting system and make your Ford Flex car won’t start or hard time to start &#; This article guides you through some of the facts behind the starting system, and the components that may be to blame, and tells you what action you can take to try to remedy each situation.

No lights on the Ford Flex dashboard

If no lights coming on in the dashboard and no other electrical consumers work, the battery could be completely dead or there is no connection between the battery and the vehicle electrical system. Check if the battery terminals look tight. If the battery is completely dead, jump starting might help.

Ford Flex the key won&#;t turn in the ignition

If the key won&#;t turn in the ignition, it could be for a couple of reasons: Often this happens when the steering is locked by the ignition lock with the front wheels turned aside or when one of the front wheels is pushed against something. In this case, try turning the steering wheel left and right while gently jiggling the ignition key &#; this might help to release the steering lock.

Ford Flex No Start, No Sound, No Crank when you turn the key in the ignition:

If nothing happens when you turn the ignition key to the &#;Start&#; position, it means that the starter motor doesn&#;t turn over the engine. Most commonly this could be caused by a low/dead battery or there is no connection between the battery and starter.

Check the battery and the terminal cable connections. If they look really corroded, you need to clean the battery posts and cable connectors or replace the cables and try to start the engine. Also check the starter. The solenoid attached to the top of the starter can fail, as well as the components inside. Replace starter solenoid, starter contacts, starter assembly or repair starter circuit as required.

The Ford Flex car makes a clicking noise but won’t start:

If you turn the key to the &#;Start&#; position, but the engine won&#;t crank; all you hear is a single click or repeated clicking coming from the engine compartment. Very often this could be caused by a low battery or poor connection between the battery and starter.

Check the battery and the terminal cable connections. If they look really corroded, you need to clean the battery posts and cable connectors or replace the cables and try to start the engine. Also check the starter. The solenoid attached to the top of the starter can fail, as well as the components inside. Replace starter solenoid, starter contacts, starter assembly or repair starter circuit as required.

The Ford Flex engine cranks over but won’t start:

There are many possible causes, but we know it is neither a battery nor a starter problem. Just remember: a vehicle will always require air, fuel, and the ignition to operate.

Check the fuel. You may be out of fuel, or the fuel isn’t getting to your engine. If the wrong amount of fuel is being injected into the combustion chamber, or being injected at the wrong time, the engine will not start. Again, this will be a case where the engine cranks over, but will not actually run. This could be caused by a few different parts including the fuel pump, fuel filter, fuel injectors, and fuel lines. Some of those options are a stretch, but do have an effect on the system. Start with the fuel injectors, and make sure they are clean.

If it’s not a fuel problem, the electrical spark isn’t getting through to the spark plugs. Check the spark. Without spark to ignite the fuel mix in the combustion chamber, the engine will not start. It will turn over or “crank over” but will never actually run.  Spark issues are not limited to the plugs. Check the spark plug wires, the distributor or module, and plug gap. These all have a huge effect on the function of the ignition system.

Car Will Not Start Problems of Ford Flex

1 Car Will Not Start problem of the Ford Flex

Failure Date: 06/20/

My Ford Flex was exhibiting symptoms described in the Ford safety recall 16s The engine stalled while driving with no warning 5 times over the past two years of ownership with the most recent occurring on 6/20/ at am. Each incident was at different speeds (30 - 70mph) but no warning prefaced the stall and you had to cut the power off and turn it back on for the car to start again. Two of the stalls were during turning operations while others were while driving straight. On other occasions the engine did not start via remote start, however no dates recorded. This recall, that describes the exact symptoms, states that it does not cover my vehicle because I have a different engine. However, the part in the recall is the fuel pump control module. My Ford Flex had the fuel pump control module aa8a-9dCA with the supplier part number e. As per the recall, this is a part that needs to be replaced. I just had the dealer replace it with the new part aa8z-9db, service history below: we have taken the vehicle to two separate Ford dealerships over the past year due to this issue. Neither dealership recognized this issue because our VIN number wasn't on the list of vins provided by Ford. I paid for the repair recommend in safety recall 16s31 out of pocket so that my vehicle will be safe to drive again. The first dealership replaced the throttle body and charged us for it. After the issue occurred again, the second dealership again replaced the throttle body since the throttle body was still under warranty from the first repair. It appears the recall does not cover all of the affected vehicles. There are other Ford Flex that have these faulty parts.

4 Car Will Not Start problem of the Ford Flex

Failure Date: 07/10/

2 issues 1) the front passenger door though closed is read as a warning "door ajar". The warning stays on at all times. It drains the battery and I have replaced the battery once since owning the Ford Flex when purchased in with just under 20, miles on it. The interior lights stay on from starting the engine until accelerated speed. The interior lights after parked stay on for a minimum of 30 minutes though it could be longer contributing to draining the vehicle battery. 2) the vehicle began to feel as if it is pulled while in commute. Not starting right away or shuts down/stalls. It has stalled and not turned over though the lights and radio work. Fortunately this has happened after being parked in my parking spot. It will not turn over, but the next morning it will start. After reading about similar issues for other Ford Flex vehicles last week with my vehicle doing the above action I replaced the fuel pump relay module. Which is located in the rear passenger area between rear passenger door and furthest rear window where the seat belt pulls from I felt I had resolved the issue. However, a week exactly later I attempted to start my vehicle when the exact scenario happened all over again. Vehicle would not start, but lights and radio worked. Left alone overnight I went to start it this morning and it starts. Through out the duration of this issue of stalling, not starting, pulling while in motion as it feels like the vehicle is being jerked there is no check engine light or when checking system the only warning is passenger seat ajar.

2014 Ford Flex Cranks but wont start

We may get commissions for purchases made through links in this post.

Ford Flex has been one of the most successful lines of vehicles. The line started in when Ford discontinued several other models and took parts from all of them to create a new vehicle that would be more competitive in the market. Though the line has been hugely successful, it has not been without its issues. We&#;ve done the research to pull together the most common problems with the Ford Flex.

A lot of the quirks that you will find with the Flex seem to revolve around the electrical system. Here is a list of the most common problems with the Ford Flex:

  • Swollen lug nuts
  • Engine failure
  • Door ajar light will not turn off
  • MyFord Touch technology is faulty
  • Throttle body failure
  • Cooling fan module
  • Electrical system
  • Power assist steering disables
  • Airbags
  • Cracked fuel delivery module

No line of vehicles is without its issues. Anytime you have to rely on mechanical or electrical systems, there are bound to be problems. Components fail designs get improved upon all the time. Keep reading to find out more about these common problems. 

This post has been updated to reflect current market information. 

A blue Ford Flex parked on a car dealership, Ford Flex: What Are the Common Problems?

Ford Flex Common Problems

Some of these problems have been worse than others. Worth noting: the following information is not broken down in terms of importance or danger. Of course, there are other issues, but in this case, they were not frequent enough to include in this list. Follow along with us as we explore ford Flex problems.

The early years of the Ford Flex, namely to , had some issues that are typical in new designs. Ford addressed some of these issues via recall. Others have been reported by owners and not acknowledged directly by Ford. The to current model years have had some problems but relatively few compared to their competition.

Swollen Lug Nuts

Swollen lugnuts sound a bit funny, but it was bad enough that a lawsuit was filed against Ford. The complaint was that the lug nuts would swell and lock. This condition made it difficult, if not impossible, to remove them.

It may not have been such a big issue for the folks at tire shops or mechanics that had tools to remove them. But you can imagine the frustration that exists for the person that had to try and change tires on a busy interstate.

The lawsuit against Ford was dismissed. As it turns out, the actual lug nuts were not the issue. Ford came up with a new design, and they kept each lug nut with a metal cap for decorative purposes. The caps themselves would swell up, limiting access to the actual lug nuts. It was deemed not to be a genuine safety issue. Everything has been adjusted now. 

Engine Failure

This problem has actually been a reasonably prevalent issue with the model, the V6 EcoBoost. There were several issues with the design of this particular vehicle.

Ford did place a recall on this. The issue stemmed from battery cables that were not secured. This problem caused an electrical arc and disabled all of the electronics on the vehicle. In some cases, owners reported pressing the brake pedal while in traffic and completely losing power in the unit. Luckily there were no deaths or injuries, just frazzled nerves.

Door Ajar Light Will Not Turn Off

This problem is more annoying than it is a safety concern. On several models of the Flex, the sensor on the door fails, and the vehicle continually thinks one of the doors is open. When owners would step on the brake and come to a stop, the vehicle&#;s electronic warning system would advise the driver to place the vehicle in park and shut the door.

For a while, the accepted solution was to clean the sensor. The actual solution turned out to be replacing the entire door and sensor assembly, as the original sensor was faulty.

MyFord Touch Technology is Faulty

A dark blue colored Ford Flex for sale at a dealership

Electronic issues have been a big hit to the Ford Flex line and the automaker in general. There are several claims that the automated system that controls entertainment and various functions of the vehicle is slow or unresponsive. This defect has caused fuel mileage problems, navigational issues, and general complaints about the reliability of the unit.

A large portion of these consumers complained that there are no real knobs or manual radio controls, and all of the commands are reliant on touch screen technology. As of now, the solution to the issue is that Ford will provide software upgrades, making the reliability of the system better.

Throttle Body Failure

There have been reported issues of the throttle body failing in the Ford Flex. This has not been a frequently reported issue; however, it has happened, and it has spanned over several years.

The mechanics in the throttle body bind up and cause the engine to shut down. This issue can happen while you&#;re driving, and it will affect your ability to accelerate. The consensus is that some of these components fail, and there is no particular rhyme or reason to them.

There have been reported cases where this issue will cause a total engine shut-off. You should be aware of this when purchasing a Flex because it spans throughout its entire existence. In the event of a full engine shut off, you will lose complete power. That includes steering and acceleration.

Cooling Fan Module

There have been instances reported of vehicles overheating while in traffic. When the vehicle accelerates to average speeds, the temperature usually returns to normal. This problem appears to be intermittent and can come and go at any time.

The usual solution to this is to have the module replaced. This fix was determined through a lot of trial and error by mechanics. Ford did not provide a suitable solution to this problem as it was just a variable and there was no specific pattern.

Electrical System

Just about everything in the Flex is controlled electronically. There has been a reported issue with just about every sensor in the vehicle. Keep in mind these reports are widespread.

When you sell so many models of a vehicle over the years, it&#;s bound to look bad just by sheer numbers alone. There has been no single cause pinpointed. Most owners have new sensors installed. There has never been an official recall by Ford for this.

Power Assist Steering Disables

This could have fallen under electrical system issues, but the severity of it warrants its mention. In some models of the Flex, namely the model, instances have been reported where the power assist steering will disable. When this happens, steering becomes difficult, if not impossible. The power steering is controlled electronically in most Fords.

There have been reports of this coinciding with total engine shutdown and loss of control while driving the vehicle at speed. Most reports of this happening occur at slower speeds. The vehicles have been able to pull over to the side of the road. However, in a couple of instances, people were stuck in the middle of interstate traffic and blocked lanes.

The cause of this has never explicitly been discovered; however, it is comedy most mechanics and shops start targeting the relay system. Ford has provided no specific solution to this.

Airbags

There have been some instances in the Flex where the airbags did not inflate correctly after deploying. Ford did issue an active recall and will work with dealerships to replace them as needed. The cause of the problem was never publicly disclosed, but it has been fixed.

The vehicles that were affected were built with the Takata airbag. If you suspect that there may be an issue, take your vehicle to an authorized Ford repair facility to have this looked at.

Cracked Fuel Delivery Module

Issues were reported about the fuel delivery module developing a crack. This would allow fuel to leak. This recall affected the Flex police interceptor model in particular. It presented an immediate fire hazard, as the fuel would leak into an area containing active electrical circuitry.

Ford has worked with its dealers to fix the issues. If you have purchased a model such as this, you should take it in and have it inspected.

In Closing

As the design has progressed over the years, several improvements have been made. Plans change, materials change, the market is always about change. The Flex has remained relatively unchanged over the years. There are some new trim packages, some different motor configurations, and electronics are ever-evolving. However, the base design has hardly changed.

This is a great vehicle to own and drive. If you are looking for a car that is going to provide you room and towing capacity, this is a good contender. You should always be armed with the most up-to-date information when you&#;re considering a vehicle. Safety is still the first priority, no matter how good the deal may be.
