I have a 95 4.3l jimmy that has a rough idle and real bad gas mileage. I found it to have bad fpr. I replaced it with new one and had no start condition. Replaced plugs wires cap rotor and cleaned/tested sensors and intake. Still no start. Put old fpr back on truck and it started first try. This is my wifes daily driver and I really need to get it fixed.
