Ok, I don't usually like to resurrect threads but my issue doesn't really warrant a new one. Regarding my wife's '97 TJ 2.5; I had started the process of diagnosing a no-start condition and I had determined successfully that it's getting spark.
I moved on to the step-by-step (as mentioned above) of diagnosing the fuel pump. First off I did it myself and had my neighbor listen, too, and there is no audible sound coming from the tank. The fuel pump isn't making any noise at all, that I can hear. I did the relay switch-around and determined that the fuel pump relay was good. I got back to the harness connector at the tank and realized I've misplaced my multimeter. Being that it's almost time for me to leave for work, I hooked the harness back together and, just to see, I tried to start it once again. A few times it might have fired once or twice and then went back to just cranking over. I tried once while holding down the accelerator and it started, rand and idled fine.
My question is, should I still continue to diagnose this? Is it still possible that the fuel pump is bad? Could I have a pump that's only working some of the time? Just low fuel pressure? To make sure I wasn't crazy I pulled the fuel pump relay out while it was running and it started dying within a second or two.
