90 2.5 YJ no spark

[wondernad]

Just got a 90 2.5 YJ and it doesn't run. Found out I have no spark. Have power and ground to the coil. Did some searches and checked the crank sensor. Looked for an ignition module that isn't there. Not sure what way to go. Leaning towards ECU. Hoping maybe I missed a fuse or relay or something. Not going to be buying an ECU. Since i'm just gonna dismantle for parts for my CJ but I want to know that the engine and Transmission are good before I put them up for sale. Just don't like to sell unknown pieces. Makes me feel shady. Any help is appreciated.

I'd swap you an ECU for a starter for one... I have a parts truck that the brand new starter had a factory defect and it self-destructed on the truck. No hope of fixing it and of course I dont have a reciept or the $65 to buy another just to test the engine so I can sell it! lol

If you were local I think I would be all over this. But in case it isn't the ECU I wouldn't want to make you wait till I figured or what the problem was before you got the starter. I see you drive trucks for the government, if you come through NC let me know maybe we can try it out.

Still no luck getting it to fire. Replaced crank sensor with no luck. Going through wiring and getting confused. the latch relay has 3 powers?




Also trying to figure out the coil wiring for the orange wire. Also the extra pin on the coil.




Anyone???

Don't know why it keeps rotating the 2 pictures to be sideways. tried to fix but no go.

Got her running today. Ended up being a bad ignition control module. Got one and an ecu shipped to my door for $65. Happy that its running. And everything seems to work.
