03 6.0 runs then dies no codes
2003 f250 super duty, 4x4, with 116,000 miles. I have had it since 30k, and last spring they rebuilt it from the block up under warranty, seems all the trips in they never got around to fixing the recall on the cooling system and it bit them in the rear. So now its out of warranty.
35 days ago fillled up on on as a cold front came in, dropped from the 70's to the 20's. It ran fine on the 15 mile trip home but had no power on the way back to town that same night. The next morning it made it to the end of the street and died, it would start but just barely, I limped it home the 2 miles. It seemed to be a fuel issue so I drained the tank and changed the filters, they were pretty dirty but no wax.
It warmed back up (50-60s) and the truck would start and run but would die occasionally. Hard to restart. 10 days ok as temp was in the lower 20's it died on the way home and would not stay running. It would run for maybe a minute then die. Real hard to restart, left it in town, came back two days later when it was warmer and it would idle but died in gear.
Changed the fuel filters again, they were clean. Started digging around and started guessing. I think its a fuel delivery problem. I picked up the pcm? Cam Position Sensor yesterday and replaced it, that did not fix it but the old pcm came out in two pieces. So I figure it is at least a contributor.
So what next, I have not done the EGR valve but thats next, I am thinking fuel pump, but not sure. There are no codes at all and has never thrown a code since I have had it.
Want to check the fule pressure does anyone know what size the port is.
I really want to take it to the dealer but we are 25 miles from them. So if I make that commitment I am about 300$ in with just towing and diagnositics, would really like to fix this myself.
