Truck wont start
This isnt my truck im posting this for someone.
It is a 2006 f250 6.0 over 100k miles.
The truck staled a few days ago and the WATER IN FUEL light on the dash came on. Drained the water out, replaced both fuel filters while we were at it.
WATER IN FUEL light went off, but truck wouldn't start. Forgot to bleed the air. So we bled the air out, still no start. There is no air left in the lines.
We used some ether to start the truck, which did start it. The truck would only stay on when reving over 3000 rpms, anything under that it would stall. We left it running like that multiple times and still stalled after.
So a mechanic came in and hooked his computer up and it said COMMUNICATION PROBLEMS.
Im thinking now that the water in fuel light was lit up because of problems with the PCM or a sensor(s), and not even a problem with water in the fuel. Water in the fuel wouldnt of caused it to stall anyway right? im not sure on that.
Does anyone know what could be causing this? Any certain sensor that would not let the truck start or stay on under high RPMS? Truck ran fine before this and just stalled one day and has been being a typical 6.0 ever since.
Any help would be great, thanks
