Hey Dude, let's go back to the start. What started your problem?

BTW the brown wire with the rubber connector should be the A/C.

Dig - for a quick test (just to see if everything electrical is working and it is a wiring error.

Run one wire from the + side of the coil to the battery and another from the - side of the coil to the dist. Turn the Jeep over and it should fire up.

Also, do you own a meter? Diagnosing a wiring problem without a meter is next to impossible!

I will try that when I get home today! I do own a meter, last night I was tinkering around and I have twelve volts going to the coil when cranking! where do I hook the negative wire to the distributor???

There really was no previous problem, I just am trying to get the jeep rewired from when I pulled the motor for rebuild!!!!

do you have power coming out of the coil? If you do you might have a bad module or condenser which ever one you have.

There is a condensor and a module which kind of confused me but anyway, so to see if I have fire coming from the coil, do I just pull the plug wire from the coil going to the distributor and see if it has fire? I know I dont have fire to the plugs because I pulled number one and there is no spark at all! I was thinking maybe the module but didnt wanna drop the 25 bucks if it wasnt the issue.......

goes like this (very simplified)

battery > ignition switch >ballast resister (if you have one) > + (pos) side of coil.
then:
- (neg) side of coil > distributor wire (if you still have points)

If you take a wire and hook one side to the + battery side, and the other to the + side of the coil, it should fire (when you engage the starter). That would eliminate a lot of troubleshooting because you know what works and what doesn't.

I tested everything and it fired! So I am going to just buy a HEI and do away with the coil and everything....do I also toss the ignition module?

I have seen them wired up with the module, but why I can't say. I personal did not. I tossed it & went straight HEI. My 401V8 runs great without it. I think it's one more thing to break & there is no way to test it.

Are you saying it started up?? If so your solonoid is bad or you have it wired wrong.

Longhorn: we must be calling a module something different as it won't run without one. It is built in to the HEI right? I might be getting my chey. and Amc confused.

I was speaking of the stock Mortorcraft module that came stock on the Jeep & is located on the drivers side inside fender panel.

well maybe this is not it , but im redoing a 79 CJ7 anyways i replaced the volt meter....and many other parts......i go to start and no fire either...after 6 hrs looking for bad wires everwhere...and a new control mod..... ext... it turned out the only power source to fuse box....which ties to everything else......... was the volt meter.....so i put old volt meter back in and damn thing started right up!!!!!!!!!

Welcome to the site shawn1979cj7!

Glad to have you aboard!

You say you replaced the 'VOLT' meter? If the gauge is wired in series to the fuse box and supplying power to it, it is an 'AMP' meter. The two gauges are not hooked up the same. If you replaced an 'AMP' meter with a 'VOLT' meter - then you are correct - that is why your CJ had no power.
