I just purchased a 1990 4.0 Aw4 cherokee
It has some starting problems. Each time I started it it was being jumped trying to start it on 2 different batteries it wouldn't start. While running If I turned anything on the voltage dropped below 12v. I took off the battery for a couple seconds and it ran fine. I drove it about half way home and it began sputtering. The more gas I gave it the more it sputtered and the RPM's dropped.
After getting it home I tried jumping it again and it wont start. It's not getting spark.
I was thinking a bad ground and maybe a CPS.
