i have a 92 jeep country and have been having a no start problem with it Here are some of the symptoms and some i have checked . It will turn over and everything but no spark with the coil wire off. I took the plug off to the coil and put a test light in one of the plug holes and got someone to turn the key on all the way and the light comes on for a second and then goes out.??? Yah i know what the @#*&! . I supposedly checked the crank sensor plug B@C terminals for H.O. engine. When testing with meter does it matter which red and black from tester goes to B@c in the plug??.So other than that i really don't know. could it possibly be the pcm not sending signal to coil,is there susposed to be constant power with test light at coil with key on or just a signal?? Well there you go that's kinda of where it's right now. Please somebody shed some new light and direction my way.. Thanks Dan.i
