Greetings, Jeep friends! I'm having an issue that has been briefed by others in past posts, but I haven't found a solution that works for me. Here are the details:
- Recently bought 1986 CJ7 with 114k miles.
- It ran fine, but there was a massive oil leak at the point where the fuel pump connects to the engine block.
- After doing some research, I removed the fuel pump and replaced the gasket (there actually was no gasket between the pump and engine block).
- That fixed the oil leak and it ran fine right off the bat that same day. However, after the engine heated up, I had some cases of "dieseling" after turning off the ignition. In other words, I turned off the engine and the engine sputtered for a few seconds and shook obnoxiously.
- Yesterday morning, on a cold start, the engine would turn over but then die after a few seconds. After a few minutes of giving it gas when trying to start it, I could finally get the engine to start and idle.
- At another person's suggestion, I closed the choke on the next cold start much later in the day, and she fired right up. However, that trick did nothing for me this morning, and the issue persisted (i.e., having to rev the engine to keep it from dying - after several minutes the engine stayed running and I was able to drive it).
- Idle is now rough - you can hear the rpms going up and down. The engine shakes more than normal
- Tachometer now inexplicably doesn't work. It did work up until this morning.
- Once I get it started, it runs fine. I can turn it off and start it again immediately without issue.
- After a few hours go by, on a cold start the engine will no longer start unless I spend several minutes revving the engine to give it gas.
I'm a neophyte here and bought the jeep to enjoy and learn more about cars. It looks like I'm getting my first real dose of experience through the school of hard knocks!
Any suggestions are welcome! Thanks, and have a great day!
