Truck wont start
Do you know if it is fuel or spark related? that would be your first step.
First thing u want to do is narrow down the problem by checking fuel pressure at rail, if there's fuel pressure, then it's not fuel supply issue. Check spark after coils, at spark plug, if there's spark, it's not a spark issue, then u will check compression at each piston. This will at least point u in the right direction
