Thanks to any response in advance. I've registered as a new user (original username is Ford-e-Tude) because I am away from home, without my password, and do not have access to my old email account to get my info....long story....



Anyway. I have a new problem, no start when engine is not completely cold. The other symptom happened later on---with accelerator pedal depressed it remained at idle.


First time problem appeared:

I drove the truck to a brief visit. About an hour later, I tried to start it, and it cranked for a few seconds, fired, and then stalled. This continued after several attempts. Each time, it seemed to fire for a few seconds longer, but still stalled. I thought I was dead in the water, and left it for about ten minutes. I went back, and it started up, and I drove it about 15 miles to mom's house without any problems.

Second time:

Next morning, I drained fuel separator. No water at all. Truck started with no problems. Then after driving about five miles, I pulled into convenience store while mom gassed her car. I shut off my engine. When I tried to start it would crank with no start at all this time. After a while, it began to sound like it was about to fire as the cranking got faster, but it did not start. So, I left it for a couple of hours, came back later and it started right up. I drove to the market to get some groceries, and left it idling while in the store. When I left I noticed a little hesitation in the first 25% of the acceleration pedal, but it ran great once the rpms were up. Drove about 3 miles, and turned into road that leads to Mom's house, and when I stepped on the pedal, no acceleration at all. It remained at idle. I coasted to side of road, and to no avail it would not rectify itself, so I shut it down, and left it there.

Third time:

I returned to the truck on the side of road after about two hours at mom's. It started up without any acceleration problems. So I raced it to my mom's house and stuck it into her garage last night.



I've read the tech folder, and have searched "no start when warm". So I am going to try to test for bubbles and exhaust in my secondary fuel filter housing and an ICP voltage test to check HPOP pressure.

I've been checking codes all the while and had none, until this point....P0299 (Turbo/SuperCharger Underboost). I suspect this is an effect of the accelerator pedal/idle problem and not a cause of the overall problem.

Any one out there recognize the symptoms? Thank you, as always, for any responses.


Fuel filters, oil filter/change, air filter......replaced 4000 miles ago. OEM filters only. 5w40 Rotella T6.

New EGR.....3000 miles ago. First one was clean after 110000 miles, but was failing electrically.

FICM has been resoldered by me, twice, and has not thrown codes since, and last I checked was at 48 volts. That was a cold start problem.

 

Check your FICM again, but I think you hit on it when you said "check for bubbles in fuel". Also check the EGR to see if it might be hung open by a chunk of gunk.

 

Thanks for the response.


Well, the test for the HPOP went well, and no bubbles in the secondary fuel filter housing while cranking engine. The EGR looked fine too.

And after all that. I can't get the truck to repeat the problem. Everything is working fine now. I think that points toward the FICM or some other electronic component.

I'm going to take a chance and make the four hour run to home. I'll update ya'll when I learn more.

*keeping fingers crossed*

 

Well...we made it home without any problems at all.


The problem has ceased to exist. Weird.



If it happens in the future, I'll post updates to this thread and let you all know how it goes. Until then....

...I'm hoping this thread is over.
