hi i bought a 1976 jeep renegade with the amc 304 in it.. the car turns over but does not start... so i replaced a whole bunch of stuff leaving me with the same problem... bassically everything is new from the battery to the plugs... still no spark... im getting fuel because i can see it in the carb and the fuel pump is making a very distinct im working noise so... i have executed the spark plug test twice... still no spark... so for a while i took a break so i didnt break the window on the car because i was getting really pissed but tonight i decided to bring the car back some love and i want to get it going... so tonight i noticed that in the car a bunch of the wires were all torn up... i have no idea whats what the hanes manual kind of sucks... but im pretty sure that the wires disconnected are for the guages... (so there not important right now) but i would like to know about the connections under there and what connects to what type of thing.. a diagram or detailed description would mean the world to me.. anything to help would be awesome... thank you all

Not a CJ expert by any means...but my '77 SJ Chief had an ignition module in it (located on the firewall or inner fender?). I would expect (but would be guessing) the CJ's had the same thing with the 304 as well. Not a cheap part, but when all else fails I'd replace it. That's what I had to do, and mine fired right up afterwards. Have you replaced that yet? If memory serves, it was like a $100 part at the time. I figured worse case is I'd have a back up because they go without warning.

Just a thought.

Several years ago I had a customer tow his 76 CJ to my shop. Same problem your having. All voltages at the module were correct and I had a distributor signal. What I found was the module grounded to the fender, the fender to the tub had corrosion (bad ground) when I leaned on the fender and had my son crank it it would fire up. I found this by accident after spending three hours checking it out. run a jumper from the module to the engine see what happens. Good luck on your quest. Geeper

Sorry, I wasn't real clear on that. You should have five wires. Red=12 volts with key on, white=distributor, blue=distributor,green=coil and black=ground. Attach one end of your jumper wire to the black wire at the ignition module, the other end to the battery negative post. I had a after thought, the battery negative would be a better place to attach to. Let me know what happens. I'm stuck at home for another week recovering from a hernia operation, so I have nothing but time. Geeper

so... somone is actually going to jump the car??? or is it that im just taking my own voltage from me cranking it... sorry im having a hard time understanding i just want to be a 100% clear before i do this.. thanks though... but bassically im putting voltage straight into my ignition rather than having it go all the way through the wiring harness and that makes sense i just dont get whether or not im connecting the black wire with the jumper cable to a positive on somones car to be jumped or if im just using my battery in my car????

haha sorry i read it really slow and figured it out.. okay yea i wasnt thinking ummm i grounded the black wire to the battery negative and still nothing....... but what i was talking about earlier was bassically somthing somone else told me .. that there should be a way to run a positive wire into the ignition module and start the car that way that way u do not have to run all the way through the wiring harrness... would u know how to do somthing like that because im pretty sure my ground is good because it didnt work when i fixed it the way u said... so now i would just like to find some way to almost hot wire the car... any ideas...???? thanks for your help so far Very Happy

does your distributor have condenser? it'll go bad and you'll not get spark.
