Problem: '94 Cherokee has trouble with cold starts.
* It will crank and crank and crank if you just get in and turn the key. It sounds like it wants to start, but just can't.
* If I let it crank a few times, turn the key back to "run", and then to "start",
-OR-
* If I give it some gas while it's cranking,
it'll start up, but idle really rough, and I have to give it gas to keep it running. After a few revs with the pedal, it's fine.
* If I just turn the key to "run" and leave it there for ~20 seconds before turning it to "start", it usually starts up just fine.
Another clue: This all started after my Jeep was involved in a (minor) rear-end accident. The tank area wasn't damaged; only the driver's-side corner of the rear bumper was hit at ~20 MPH by a Honda Civic as I was slowing down to make a right turn.
I think it's the fuel pump. Maybe things back there got shaken up just enough to cause the pump to go bad? My friend says it could be the regulator and/or filter as well.
Anyways, first question: Where's the regulator?
Question B: Wouldn't the pump make some whining/squealing noise if it were going bad?
III: What else could be wrong? CPS?
