I have a 1995ish 4 liter engine in my older 1987 YJ. It had no spark so I put on a new coil,new crankcase sensor ,new cap,rotor and wires. It,s real strange after each new part I think it,s fixed as it starts but eventually it,s the same...... no spark. My son says it has no ground into the coil but there is positive power [at the 2 prong connector going into the coil] Anyone have any ideas before I bite the bullet and take it in?????? Sounds like a bad connection or loose wire maybe but where???????

You mean CPS, the sensor on the bell housing? Crankshaft position sensor? If not I would do this first, then check the pickup in the bottom om the distributor.

think I may have found the problem,I looked at the ecm under the hood on the drivers side inner fender. It was full of mud and I cleaned the terminals etc and it fired up. Not sure if this is the final cure or not I should know in the next few days
