How did you test it? Did you use a fuel pressure tester? If you just pulled the line and got fuel it could be residual pressure. I think it should be about 35psi at idle.

The way I checked it was I unscrewed this cap off the what I think was the fuel rail (metal tube running parrel to the engine) Please excuse my ignorance for the proper terminology of what the parts are called. I'm learning as I go. Anyways I unscrewed this small cap and my buddy told me to turn the key to prime the fuel pump, once I did that he pressed down inside where I unscrewed the cap and lighty pressed against this valve thing. When he did a small amount of gas squirted up. I turned the keys off and reapeted the process with the same outcome. My buddy said he thought my fuel pump was good after we checked that, but I know he's not a mechanic or anything.

Oh yea one other thing I found while looking my engine over was that my cap and rotor where very damp. There was moister and oil residue inside of it. I know this is bad. So I pulled the pieces I could and cleaned and dried them. Put them back in but still when I turn the key my engine just cranks and cranks, no ignition.

Yah, that's not the most acurate way to test yur fuel pump. lol. Narrow it down. Make sure its not your spark. If you have a timing light see if it works while turning the engine over. If not, take a screw driver, unplug your #1 spark plug and stick the screw driver in it and hold close to the motor to ground and see if there's a spark while cranking engine. If no spark, there's your problem.

If there is spark, it's probably a fuel issue. Go down to Autozone and rent a fuel pressure tester.

i use to do this test with the screw driver till the day i tried it on my mustang....With a MSD BLASTER coild and MSD IGN box...it threw me off the trailer.....i now use inline spark testers.......however a stock jeep ign would be a little zap.

Well got it fixed...turns out it was my distributer that went out. A peice actaully broke off it. Put in a new one and it fired right up. Im wondering though, it seems like everything that can go wrong in this jeep will go wrong. What else on Cherokee's tends to break a lot, like parts under the hood. So far I've had to replace the altinator, distributer, steeing shaft (the long thing under the hood, haha dont know its name), the entire exhaust due to rust (didnt mind putting that in though, sounds great now) and who knows what else in the future. Any thing that you guys know that tends to go out a lot in xj's. I just need a heads up because this cherokee is turning into the perfect example of what JEEP really stands for (JUST EMPTY EVERY POCKET)....
