2005 6.0 wont start
For a year I have been dealing with this problem by not dealing with the problem, and now I have to.
For the last year, the truck would start 95% time, but that 5% it would crank and not fire but ten minutes later it would start, and it would happen when warm and cold. However, it would pop start on the slightest of grade or behind another vehicle. Recently my buddy was using it, killed it at a stop light, and had to get it pop started to make it home. It hasn't started by cranking since , though it has started by pop starting.
a week ago i had to use it and pop started it, and 5 miles later i started loosing power for the last mile, then it shut down. I had my buddy tow me back to town and it would start and die periodically, but then start again. It seemed like it wasn't getting any fuel, so I replaced the fuel filters. We pop started it again, and it fired right up with no effort. After about 20 minutes of idling to get the air out, it was starting to sound like it was running great. I hit the fuel peddle to increase the rpms and it simply died with no throttle response. Hasn't started since even when trying to pop start. Finally got the shop over here to run the codes, and here is what I got.
My engine cranks at 140 rpm, but it isn't plugged in and is 20 degrees out. There is oil pressure on the gauge, and IPR gets to 85%.
Cam and FICM are showing synced and the PSI when cranking is 464.
I was going to get down to the FICM and test the voltage, then work my way back to the IPR and pull it (I replaced it a year ago)...
Am i on the right track or does someone have another course of action that would be better.
Thanks in advance,
