Thanks Squisher. That link has some same problems mentioned. I am going to forward it to the dealer to look at. I will update with status.

Here is the link for anyone interested.

If they can't replicate or diagnose the problem just keep it in mind if it happens to you again. I'll be interested to see if this problem crosses over engine platforms.

As far as know those of us who have moved the multipin connector off the parking brake assembly have not had the issue reoccur. I am quite sure another diesel owner had the same issue.

 

I hate to suggest on fixing your own truck while still under warranty but sounds like you have the same problem as the gas powered trucks. Take the big harness attached to the parking brake bracket, unplug it and reconnect it. I'll put a solid bet the truck will start and not act up for a good while. This is becoming a all too common problem. I don't know exactly which wire in the harness causes the issue. I got tired of screwing with it and zip tied the connector away from the parking brake bracket and haven't had a problem since. Also if you disconnect that harness and try to start the truck it will give you the symptoms you are talking about. When the truck acts up it likely won't scan or connect and give codes either because I tried it when mine acted up. That is like why they replaced the pcm. One of these days I'll look into what wires go to what in that harness just too busy with everything else...hopefully ford does something about it

 

I shared the information and the link that talks about the wire harness to the dealer. I even went to the dealer yesterday as they claimed the truck starts with no errors or check engine light. When i got there the truck started just fine, i proceeded to press the back down and start then release as i normally would and start. I was unable to reproduce the symptoms the couple of time i tried.

I had the mechanic disconnect that wire harness and tried to start it, boom same problems I had and truck would not start. We connected the harness back together and the truck started with no codes or errors. Hopefully they will take that information and try to resolve it. However I have a feeling i will have to do as other said and just leave the harness zip tied off the bracket.

I will keep everyone updated as I have not heard from the dealer today.

 

The good news is that all of us seem to have had a good dealer experience if not effective: they have all tried to resolve the issue and have been willing to go the extra distance.

It is very easy to remove the connector from the brake bracket and wire it up so don't be afraid to do it yourself.

 

If they cant find out why it is causing this, then I will remove it from the bracket and zip tie as everyone else has.

 

Using the parking brake is the cause. The violent release is causing issues withe the harness. From the day I bought my truck the air bag light would flash when I released the parking brake. That and the no start is what keyed me into looking at the connector. Played with the harness and the truck starts and no air bag light anymore

 

Yup, projectnitemare should get a reward from Ford. At least one person in the forum was looking at having Ford but back his truck due to this issue.

I have a buddy who put a new Mustang back on his short list of cars he is looking at after taking it off when my truck died and the dealer could not definitively diagnose or resolve the problem.

Thanks I told them about that so hopefully they will either find what connector or replace the harness. If not I will just remove it from the bracket assembly.

I agree, seems there are numerous of people that have demonstrated this probably in some sort of fashion.

I am still waiting to her back from my dealership. After telling them of this, they simply stated we can't do anything until we duplicate it (even had them disconnect the harness to duplicate) and they are waiting to hear back from ford.

 

Hmmm. I'd think if a tech spent some time with the truck running and wiggling that connector or messing with the park brake that they'd be able to replicate the issue. Also pulling that connector apart and checking all the pins and ensuring a good contact and then moving it off the parking brake assembly would be a good start.

Please keep us updated with the outcome.

 

Just got off the Service Adviser and they waiting to hear back from Ford to see if they can apply an overlay (bypass for pin or connector). We update if they get the approval and will provide the specifics.
