Give the truck to your wife it likes her better .

It could be a number of things from a leaking o-ring on the HPOP system, poor fuel pressure, weak batteries, failing FICM and the list goes on. you really need to get it on a good scanner that can run tests and monitor sensors to narrow it down.

I want to say thank you for your post. it made me laugh in a other wish really bad day.and after reading that my day started getting better.well when i got home the truck started and runs fine started many many time always fired right up.so im at a lost.

I'd say leaking through injector o-rings by the sound of it, same thing happened to me. But it definetly sounds like a high pressure oil system leak

I had the same exact problem and 1 day it wouldnt start anymore after it was warmed up. Heres my post/convo with someone about it. p2291 help

Hey thanks for the link.when i can get to a computer im going to check it out.im wateing for my buddy to get his scanner back from being updated.i have a real good feeling it is a hpop leak. and after the scanner conferms this. im just going to change out all the o rings while im in there. if the leak is around the injecters i might just get some upgraded one or new cups.plus at this time im going to put in my egr delet ,new turbo drain tube,ccv mod,smoke swith etc etc. seeing that ill have it torn down this far i my as well

Ok with a build date of 03/04 my truck wont have the stc fitting right? also i just had my egr cooler and oil cooler replaced so is there any lines that the tech could have bumped around to make this thing leak? i still havnt got the truck scaned yet. but the fact that it didnt start again today.so im going to call the guy and see if his scanners back and when he can get me in

I'm gonna say its the two 10mm allen plugs in the front of the oil rail. The o-rings on those go bad ALL THE TIME and cause a high pressure oil leak when hot. When the oil is thick and cold, it compensates for the damaged o-rings, but once it gets hot and thins out, it will cause a no start when hot. you can usually crank it for about 20 seconds and it will start up. monitor your ICP level after its hot and you shut it off. You have to have 500 psi to fire your injectors and usually what happens is your ICP will sit at about 200 forever and finally build up enough pressure. I work at a Ford dealer and thats the most common problem we see for no start when hot.

Ok thanks for the heads up. now i need to do a update for u guys the truck is now a full on no start at all. also my build date is 03/04 but my icp sencer is in the pass side valve cover.so im thinking its a 05 motor which would mean i have a stc fitting.now is there anyway to see this fitting with out diging in to the thing?

[firefighter317]

not really. just pull the valve cover. you can have it off in about 30 minutes or less. but like I said, id say its the plugs. We have a fitting that screws into the ICP hole and we apply shop air to it. Do this when its hot and doesnt start but now it wont start to just do it whenever haha. If there is a high pressure oil leak, you will hear air coming from it. If it turns out to be the plugs, replace both, not just one. The other will usually be quick to follow.
