I am working on a bone stock 04 F250 6.0 that does not start. It has been running rough at startup for the last few months. It was driven about 20 miles on its last drive and now it wont start one day later since its been parked. I just put two news fuel filters in it since the owner has never had them changed in its 130.000 miles. This however did not help the no start issue.

The truck has four codes;
Po401-EGR
P1328-i believe to be from a leaky ex. Manifold
P2290-ICP sensor too low
P2614-camshaft sensor...due to repeated no starts I believe
P2617-crankshaft sensor...due to no starts I believe

The truck turns over great. When batteries are charged good the engine just cranks over but as the batteries die and the cranking slows a little bit the truck will pop like it wants to start. Its weird how it does not pop at all when the batteries crank fast. I tried with ICP unplugged and that did not make a change. I do not have access to a scanner such as AE but I can work on a 6.0 pretty good. I did a hg in cab. on an 03 last year

 

What kind of fuel filters did you use?

 

i used the filters the owner supplied....napa brand

do you think not using the motorcraft filters will make it still not start? I know in my old 6.0 i used nothing but motorcraft

Heres a link for you. I would stay away from aftermarket filters. I would only use motorcraft or ford filters. Could solve all your problems. Hopefully.

 

I know you're supposed to only run motorcraft filters but if.it can run on a stock fuel filter with over 100000 miles wouldn't it still run with any new filter if that was the issue?

 

I forget which filter has the plastic piece on it that pushes down a button at the bottom of the bowl the fuel or the oil but most aftermarket ones dont have that piece to push that button to allow fluid passed it. ill try to look more into it and get you a better answer or mike can come along and help you out a lot better than i can

 

If he's using Napa fuel filters, he's probably using napa oil filters... and they're JUNK. They're the one's jeff is referring to, they don't seat in the oil filter housing correctly (they have their own cap even) and they wont pressure the button in the bottom to allow oil in. I've seen then cause poor running and even no start conditions. I'd look into that.

Are you sure that P1328 isn't a P123B?

The ICP sensor too low is of interest, I can't help but wonder if the high pressure oil pump crapped out. It seems on the 03's and 04's they tend to die out a slow death and cause poor running like you're seeing and the 05+ usually have a sudden death.

Easiest way to check that is with a scanner, monitor ICP actual, ICP desired, and IPR duty cycle. If you can't do that, pull the IPR valve out, if it's got a bunch of metal shavings on the screen, the HPOP is dead. When you're cranking can you see the low pressure oil gauge on the dash come up? It will usually take a good 5-6 seconds of cranking for that to move.

Your assumptions about the cam and crank sensors is most likely right, they're falsely thrown all the time with a bunch of cranking.

Regardless of whether it's a "fix" for the problem or not, I would strongly suggest to the owner to use motorcraft/international fuel and oil filters ONLY.

You're not too far from me either...

 

Yes the code is p132b.

I wish I had a scanner so I didn't have to pull the ipr...its such a pain, however thats the only next thing I could think of to check

 

p132b is a turbo code, probably needs to be pulled and cleaned.

I do have a scanner and am not far from you, but not sure when I'd even be able to get out that way.

 

Yea the turbo code im assuming is from the leaky exhaust manifold.
