This is concerning my little brothers truck. He drove it to work today, ran fine. This afternoon he went to leave and the truck starts, idles smooth as butter for 5 seconds max then dies.
Truck is a 2008 F150 with the 4.2 liter and 55,000 miles.
Before I could look at it he and his boss replaced the fuel filter as the original was on there and it was time anyway. The battery was also replaced, also original and bad (eye was red). No change after these were replaced. Fuel in the old filter was dirty.
Checked the fuel pump driver module as corrosion is common on these in the F150, no corrosion. Fuel pump also runs from when key is turned to on until it dies.
All fuses are also good.
It got dark on us so I just brought him home. Tomorrow we are going back to further diagnose or tow. The only other things I can think to check is the MAF, and fuel rail pressure sensor. Anything else can be checked while we are poking around? Any ideas on what could cause this? Im open to trying almost anything to fix it where its at. Thanks in advance for any suggestions.
