I just got a 88 wrangler 4.2 5 speed it ran just fine until the other day. I parked it and next time I went to start it it doesn't fire it's spins over just fine. I've already replaced the ignition coil and the distributor and still no fire any help would be appreciated.

 

Thanks for the help guys I diagnosed a ****ed up ECM and replaced it. Like new. Running on strong with some needed parts replaced love it.

Now to fix the frame on the XJ
