do you really need 2 threads?

If it has no spark but has 12v then it has to be the box under the coil. It's rare that coils go bad.

What is your fuel pressure? Check it with a gauge...

OK if all the things you list tested out good then the ECM plug should be cleaned and if it is clean and you are sure of it's integrity then the ECU may be faulty. I have never seen but one that was bad and it was due to welding without disconnecting the battery.

I would say the Ignition control module would be the first thing I'd check next. Its the box that houses the Ignition coil and if that goes bad then no signal can get to the Coil. Is it turning over but not starting? like no spark at all?

Correct me if I am wrong Blue. But if I have power to the tps, ignition module, fuel pump, etc Wouldnt that mean the comp is working.

I have worked on alot of cars, and built alot of cars. This is my first jeep, and they have a mind of their own.

Have a brand new ICM.

Has a brand new Icm. It is turning over but has no spark at coil.

Whatever it takes to get this thing fixed!

Have you checked all the wires that go into the ICM or spark plug wires as well?

Yes the icm has power, and a good ground. The spark plug wires will not get spark if the coil isnt sparking. I have 3.5 volts to the cps. I have 12 volts to the icm/coil. All the fusible links are good. I dont understand it just quit and everything checks out. I need a big cliff. LOL

ok you have power going to the CPS but have you tested the resistance of the CPS to make sure its good? You can do that by following the steps here --->http://www.jeepforum.com/forum/f11/9...ew-cps-924600/
about the 2nd or 3rd post I believe. Also did you check to make sure the CPS didnt come lose off the bell housing?

I have checked the resistance on the CPS. It was at 215 Ohms cold. And yes the CPS is tight.

Well I have no idea man. The only things I can think of are spark plugs, spark plug wires, Distributor, Rotor, Distributor cap, Pick-up coil, Ignition coil, Ignition control Module, wires going to the ICM, Crankshaft positioning censor, ECU, and Battery. oh I just thought of something. There is a black wire on the bottom left of the engine block that bolts to the frame somewhere. Its a grounding wire and if thats not getting good contact it wont spark... check that. if not just let us know when you do find an answer.

oh and one more thing. I know we have fixed timing but if a tooth on that gear broke the chain could slip, put it to top dead center and take the distributor cap off and the rotor should be pointing at either the number one spark plug wire or the number 6 depending if your on the compression cycle or the exhaust cycle.
