Re: 96 XJ starting problems returned
Fyi ...testing today shows that the 2 week old fuel pump has failed ... which really really p****s me off.

'96 XJ 4.0 litre ... starter turns, dashlights light, no check engine/trouble codes appearing ... but will not always fire up
1) Two weeks ago had the above starting problems ... and finally the jeep would not start at all so to my trusted mechanic who looked it over, then replaced the fuel pump/regulator and filter. Drove around for 2 weeks, no problems and the jeep is now starting first turn of the key .... the way I expect fuel injection to work.
2) Thursday night ... starter turns etc and maybe on the 8th try, the jeep starts up and runs perfectly normal.
3) Saturday morning for the heck of it, I disconnect the crankshaft position sensor (CPS) to see what the symptoms might be ... exactly as when the jeep won't start ... so I cleaned the connector pins as best I could, applied WD40 to it, and figured that was that. Drove around all day doing chores, no problems.
4) Saturday night jeep won't start ... it's dark, I go into the house, pour a double and watch a movie.
5) Sunday morning, questions.
Q1) Has anyone had a crankshaft position sensor (CPS) fail such that the jeep will sometimes start, sometimes not ,,, and run perfectly once started?
Q2) Could the problem be the camshaft position sensor (located on the oil pump)? Is it worth my while to clean that connector?
Q3) Is it worth my while to start checking/cleaning all connectors to the computer (PCM) that I can get at?
Or just take it back to my trusted mechanic for follow up on the fuel pump which I'll do later in the week anyway.
Thanks
