Hey guys, I just picked up this 83 cj7 in a trade last week. I haven't had a ton of time to look at it, but it's driving me bonkers. I was trying everything I could think of before I posted a question on here as that's all I feel like I ever do here because I am finding out I know absolutely nothing (wife has been telling me that for years, don't tell her I admitted to it
So, picked this thing up, guy said it hadn't run for 2 years, who really knows, right? He was trying to get this old jeep out of his way. So, I thought, clean up the fuel system, crank it over and enjoy. Not so much. It seems like it fires on one cylinder and the rest are dragging. Fires once, so I let off the starter and nothing else happens. If I hold on the starter it just keeps firing that one time in rhythm, same feel, same sound over and over and over and over. Even when I pour gas down the carb, same result.
So far I have changed: fuel pump and filter, distributer cap, rotor, plugs, wires, and coil. I know I have been throwing parts at it, but they are all fairly inexpensive and after two years it wouldn't hurt.
I have reversed all my plug wires 180 degrees, definitely not the issue. I pulled all the plugs out, laid them against the block one at a time and turned it over and I'm getting spark, some seem stronger than others, but that was before I changed the cap and the coil, haven't tried that again yet. Also not 100% sure I had them laying in a clean grounded spot. I plan on checking compression but I need a second set of hands for that so hopefully in the next 2 days I can get a buddy to come help me with that.
What am I missing? Is there an obvious problem I am overlooking? Anybody had anything similar happen to them? I appreciate any help at all, I have learned quite a bit on this forum in the last week doing searches of possible issues and have tried to weed through them. Thanks for your help in advance.
