Okay, I have gone through all this issues to deal with why my '91 XJ won't start. I have replaced all the starter and ignition systems, the fuel sysetm works, new distributor, cap, rotor and plugs. Still nothing. I have chased my sensors and they all have the proper ohms, volts and/or resistance.
I have come to find that maybe I should look at when it stopped and what I eventually found. When I did get around to pulling the distributor out, the teeth were ripped off of one side of the shaft.
What would cause this to happen? I have had an excesive amount of blow-by, to the point that my air filter was dripping with oil. Could this have cause the oil pump to lose pressure and cease? I turned the oil pump with a screw driver to set it up for when I dropped the distrubutor back in, it rotated without any problems. I never noticed any issues with the oil pressure guage when I was driving it. I always kept it full of oil.
The camshaft did not apper to have any damage when I checked it threw the hole. It does spin the rotor when I turn it over by hand.
So here I am. Do I have a shot oil pump, thus causing my no start? Or is my camshaft toast?
Either way I think I am going to have to rip this down or sell it for parts. I have already replaced the timing gears and chain. This is what the "mechanic" said was wrong. I thought so, until I pulled my distributor.
If anyone can help, it would be much appreciated.
Thanks,
Hoddie.
