94 4.0 ZJ, no spark
Hey guys. Little background.
I just had a 94 ZJ given to me. It's a 4.0 with 150k miles on it. Anyway it doesn't run. It's been sitting for a couple years, ran great when parked.... Here I am.
I put a fresh battery in it today and swapped out the crank sensor. I still have no power going to the coil. After I was done working on it for the day, I realized that I don't remember the fuel pump purging. The motor cranks over awesome.
I really don't know where to go from here. I don't want to jump into a new ecm for no reason.
Any help would be awesome.
