Hi,
My Dad owns a 90' xj 4.0, aw4, 242, that won't start. when we bought it it had a bad computer that caused it not run very well. it has pulled this no start trick on me once bfore but after i let it sit it fired right up. here is what i know.
It does NOT have spark.
It does have fuel preasure.
It cranks pletny fast. (enough to build 60 PSI oil preasure)
It has never started well when it was cold (20 and down)
what i would like to know from any one who knows, is how can i tell if this jeep has eaten another computer. Is there away to see if it has an injector pulse with out specail tools, and what would cause a no spark condition. these are the parts that i can think of that are possible causes can someone tell me if any of these parts would cause this and if so what would be most likely, Ingnition module, Coil, CPS, Sync Sensor, Computer.
Thanks for any help
