So a couple weeks ago my Cherokee (94/4.0/AW4) wouldn't start. It was very cold and the fuel that was in the tank was several months old so I chalked it up to condensation. I did think to check for fuel pressure and I had none. Since then I've gotten it to start by fiddling with the key but what I know is that I am not getting good power to the fuel pump. It will not always prime until I fiddle with the key and or gas pedal. I've read the "No start" write-up and am looking for some additional info on where the ballast resistor is; maybe a picture. Also where the fuel pump relay is located. Today I was going to check on some voltages and couldn't find the resistor so... However I was sitting in the Jeep and had left the key in the on position and after a few minutes I heard the pump prime. I thought it was weird that it primed all of a sudden. The only other symptom I can think of is that when the pump primes the first time it sounds rough; like it's clicking. If I turn the key off and then back on it will sound normal when it primes from then on; until the next time it doesn't prime immediately and needs played with. Once it starts it seems to run fine. I'm open to suggestions on what the problem might be and would love to have some more info on the items I mentioned above.
