There is a ground wire that attaches up above the battery tray. It attaches to one of the bolts that you needed to remove to release the heater box. My guess is you probably either have a bad ground at that point because you forgot to hook it back up, or you painted that area and need to expose metal so the ground is better connected.
Double checked that ground wire that lucca spoke about, it wasn't ever removed.. thanks louie4 I will try that next.. the only other thing that I noticed, that there is a (relay)? near the battery box, where the power wire off the starter goes into,, it had gotten wet from the anti-freeze when I removed the heater core hoses from the firewall. that could be something but idk.. it's just really wierd, because I didn't really mess with anything electrical in this process.
OK, checked everything! can't find the problem, I replaced the starter relay, coil and battery. The distributer looks good. idk still won't start just not getting a spark. Bought ready to pack it up and trailer down to my mechanic
Got the jeep back up and running. It was the simplest thing, as they usually are.. The ECM somehow came loose when I pulled the heater box out, took the mechanic 30mins to figure it out. and back on the road I go. Thanks everyone for the help.
