I've changed the fuel pump, the fuel filter, the relay under right passenger tire, the crank sensor, and the indle regulator sensor, the part in the truck left hand side, the fuel pump modulator. It's getting spark, it's getting fuel but won't turn on. It starts, reves up, sputters and then won't stay on. This car is driving me insane. It went from driving perfect to out of no where just started sputtering. When I finally got to where I was going turned it off and then it wouldn't start. That's when I did all the changes, and it's turns on, but will sputter and then turn off. Does anyone have any idea what this could be. I'd really like to know and hopefully some how get it fixed, I'm going crazy and it's frustrating as he**.
