Hello Yall,
I've been having some serious issues lately with Bob (1984 CJ-7, with AMC 304 and GM TH400 Auto Tranny).
1- About a month ago, the jeep kept trying to start with no key in the ignition
Solution: I replaced the starter & the starter solenoid...That took care of that issue
2- a week later, I started the jeep, it started with no issues and let it warm up. 5 minutes later the engine shut off on its own. I tried to start it, but it cranked without starting.
3- I added about 5 gallons of Octane 87 (gas for my John deer, and sprayed some starter fluid in the carb. After a few tries the engine started and ran smooth.
4- I shut off the engine, but a few minutes later when I was ready to take off, I couldn't get the jeep started...Sounded like "No Spark" issue to me
5- I replaced the pickup coil inside the distributor, and the jeep started immediately
6- I adjusted the timing (5-7 degrees BTDC) and adjusted the fuel mixture screws until I had about 18 PSI on the vacuum Gage (Motorcraft 2100 2BBL carb)
7- I went for a drive, and the engine ran like hell...coughing, hesitating, and jerking real bad when I pressed the gas peddle, it seemed to run better if I just maintained a steady speed
8- I change the Ignition module, and that reduced all the symptoms above drastically...I thought I was done, and might have been bad gas (the five gallons I added in step 3)
9- I decided to drive the jeep this week in order to burn off the gas I had in the tank and make room for a fresh tank of gas
10- The jeep had a slight cough at lower speeds, but once I got to 45 it seemed normal
11- Coming home from work today, while taking off at a red light the jeep backfired at the carb, but did not die, and seemed fine. I was able to accelerate to about 55...Then with no warning the engine just died!!
12- I tried starting the engine but had no luck and ended up having to toe it home
Note:
I confirmed the battery and alternator were good (Alt: 14.34 while running)
For those who are not familiar with "Bob", it originally came with a151 cubic inch and I ended up installing an AMC 304 and a GM TH400 Turbo from a 1978 jeep CJ-7
I am wondering if I need to take a close look at my distributor and ignition coil...What tests can I run to narrow this issue down
I appreciate any tips
