ok, this is starting to bug me that I can't figure out where the problem is. My 97 wrangler 4.0 will turn over like there's no tomorrow, but It won't start. I have fuel pressure, so next I looked for spark. I pulled a plug wire out, and no spark there, I checked the wire off of the coil, and no spark there. I put in a new coil--still no spark. I just put in a new crankshaft positioning sensor (cps) and still no spark to start the engine. SO what now---I'm running out of ideas--it ran fine yeasterday and now it's dead???

Had same issue with 94 wrangler. check all grounds and clean up and tighten your battery cables, especially negative. and you would be surprised what lil corrosion will stop it from turning over. I had barely paper thin coating of it around my negative battery post and it prevented spark from happening. good luck man i hope this helps
