Ok, important stuff - 96 cherokee sport, AW4, 4x4, 4.0, 160k
Been running fine for the most part. I say most part, because if you accidentally hit the gas pedal while starting it, it would become rather hard to start. Otherwise, turn the key and she starts right up, plenty of power, no overheating, nothing to cause any concerns aside from the blasted windshield washer fluid low light that always seems to be coming on.
Today, when I go to leave work, I accidentally bumped the gas pedal, and she started her acting up crap again, except this time, I can not get it to start and stay running. Normally, I just crank it with the gas pedal floored and as soon as she starts, let off the gas, and all is fine.
I can get it to start with the pedal floored, but it will only run for a few seconds, and no way will it idle....almost like it is starving for fuel, and I can hear the fuel pump running all the time (as in it never seems to build up pressure. I also notice a lot of smoke out the tailpipe (mostly blueish), and a wierd smell from the exhaust, almost like burnt gunpowder.
I figure the fuel pump has come apart, so I have her towed home.
Put the gage on the fuel rail to check, and I get 50 psi, and the fuel pump is still no turning off. Reading while trying to crank it bounces from 40-50 psi.
Hmm, now where to go ? I have spark, but not sure if it is consistent or not though.
Anyway, looking for ideas on where to start. I was sure it was the fuel pump, but not so much now......
