1990 Jeep xJ 4.0.

Did the Dizzy reindex per ( at least I believe it did ) per Cruisers instructions. I’ll ad pics of what I’ve done. Anyhow, put it all back together and cranks but no start. 🙄

I literally just drove it. Ran better but had all the indications listed on Cruisers suggestions it needed the indexing.


-Tested the new CPS, get the 5 Vac.
- Tested the spark from Coil to Dizzy cap, no spark.
( did the coil/ICM refresh few days ago )
- Removed the coil and tested ICM pins. 12+ Volts at the positive ignition on and .00 ohms at the ground.
- Testing the coil between the Positve and Negative I get 0 ohms (Not sure that’s good?)


When I initially pulled the distributor I noticed it had no O-ring or gasket of any kind. I reinstalled it with a new O-ring. It was a senior thick O-ring. Does the Distributor ground to the Motor by chance?

I ordered a new Coil but won’t be in till tomorrow. Just seeing if I tested the coil correctly and wonder if anyone else has any input.

Thanks



Original marks, now re-indexed

 

The dizzy doesn't need a ground.
Have you ohmed the coil wire?

 

THANK YOU CRUISER FOR THE REPLY!!!

Yes sir I did. Although all new wires, I did test it and it reads 0.00 ohms, moving it around and all that no change.

I hate throwing parts at things but, I kept reading conflicting information as far had the coil test. Acquired a new coil and the first thing I did was bench test it and it tests the same as the original. Put it on and of course still nothing.

I was just searching for a wiring diagram or something to tell me what to test at the plugs for the coil.

again THANK YOU!

 

Got it started... unplugged the CPS again and retested. Subsequently I thought I would ohm out the engine side of the plug. Seemed one side was reading high and erratic. (5-30ohms) All I did was push in the pins a little on both sides and plugged the CPS back in. Fired right up.

Ideal much better higher, lot snappier much better. Still bucks on occasion warmed up though. BACK TO WORK
