Just bought this truck and I inherited this problem. It will turn over, it will start (sorta) and then dies. If you pump the pedal, you can keep it running, but very badly. I have verified fuel and pressure to the rail and I have spark. New TPS, fuel filter, fuel pressure regulator, dist cap and rotor. If I turn the key and let the fuel pump prime a few times it acts like it wants to run but after a few revs of running it dies.
Any help would be very appreciated...as I am not having fun.
First thing you need to do is pull the engine trouble codes and post them. Knid of sounds like it may be the idle air control valve is part of the problem, but if you pull the codes it will help greatly in determining the problem
Matt, the codes were 22 63 & 47. At the time, I had the TPS off of the truck and I assume that was the reason for the 63 code. I installed a new one with no results on the issue. Will the MAP sensor cause those symptons?
Pull the codes again before you buy the parts and make sure they are consistant since you changes the TPS. O2 sensors are relatively cheap and it can't hurt to put a known good one on, same with the MAp
