Hi, I have a 1999 GMC Jimmy w/ 4.3. I just got back from a 10 day vacation and I cannot get the engine to fire. I have used a fuel pressure gauge at the fuel rail and have confirmed 62psi when I turn the engine over. I have also verified that there is spark coming from the coil wire. I have also confirmed that there is spark at the plugs by pulling off the #1 plug wire. The engine will just turn over with out any attempt to fire. I have also tried pouring fuel into the throttle body and spraying starting fluid as well. Does anybody have any suggestions?
