Hello fellow jeepsters I'm new to this great forum I hope someone can help me

I've changed everything in my ignition system, (1979 CJ5 ) Coil(motorcraft upgrade),ballast resistor, & Ignition module. My plug wires cap,rotor and plugs all new. I'm not getting spark. The only thing I haven't done is change distributor. I'm being told that the pickup is probably shot. How do these go bad ?? I've check continuity in the pickup and it seems to be ok.

I recently parked the jeep so I could repaint it, up until then she was running like a clock, I didn't do anything to the motor, The only thing I took out of the ignition loop was the tach, I reinstalled the tach since then.
I did notice that my Ignition mod was melted in the back, and the coil was rusted to hell (it was mounted on the firewall in a bad spot where water was steadily dripping on it), that's why I replaced both, plus I had somehow burned the coil fuse at the block. (possible burned out wire,? I'm reading 12 +volts at the coil wiring)It also seems I have continuity throughout all the ignition wiring. The only thing I haven't changed was the distributor. Do the distributor pickups fry ?? at this point I'm freekin stumped. Thanks in advance.
 
There are 3 wires coming out of the distributor, black,violet, and orange, If I remember right on the colors. The resistance between the orange and violet wires should be 600-800 ohms. The orange and violet go the the distributor pick up coil and the black is the ground for the ignition control module. If the icm does not have a proper ground all the way to the battery, you will fry it. There are remanufactured distributors if you want to get one.

Thanks for the reply, I'm gonna just go ahead and but a new distributor, they're about 45 bucks, hell I've replaced everything else out.

Don't shotgun this problem. Lets troubleshot. The whole distributor isn't bad but the pickup assembly could be. Listen to Torxhead and check the pickup assembly or check out this link: http://www.jeep-cj.com/forums/f99/engine-wont-start-troubleshooting-guide-19494/


yeah i did the team rush 4 months ago
Oh, that's important. Did you install the MSD ignition module?

No I didn't but I didn't have any problems with the stock module before I shut my jeep down 3 months ago( I repainted) . It ran amazing. Btw I went through the troubleshooting guide, great thread. Tomorrow i will be following up on the tests
