went for the xj yest morning, turned over fine but no fire. stupid thing. 1990 xj limited w/ 4.0 auto, 4.0 is a swapped ho, but running all renix sensors and computer. i checked the spark plugs, looked wet, smelled like fuel under the hood after cranking, so i believe it was getting fuel. wanted to pull a plug and check for spark, but didnt have an assistant to crank engine for me.has been running poorly when cold lately, so i assumed it was my poorly mounted tps. checked and adjusted tps, was a little off, didnt think it would cause a no-start but need to adjust it anyway, but no change. unplugged and re-plugged cps, no change. checked cps w/ ohmmeter, had 215 ohms, all wires look fine. checked wires all over engine compartment, didnt find anything suspicious. swore a little, no change. gave up. went out this morning to swear at it some more, checked for 12 + to coil, was good. was going to pull a plug and/or coil wire to see if/ where i had spark since the wife was home, but thought i'd just try it and see if it would fire and it popped right off just to piss me off. tried it a few more times and it starts fine. stupid thing. i looked at the coil to see if i saw anything obvious, jiggled some wires, didnt find anything. any suggestions on what to check if it does it again, or something i can check now. been on these forums searching half of yesterday till 2 am, can find anything else. i belive it wasnt getting spark, but dont know why, cps is good. also, its been running poorly when cold for a few weeks, once its at operating temp its fine, but doesnt have much power, kinda feels like a miss till then. adjusted the tps today and it stil does it, was sure that was the problem. seems to be running rich, plugs are fairly black. runs fine when warm though. sorry this is so long, have to vent somewhere, and the dog quit listening.
