I have a 1989 Cherokee pioneer 4.0 automatic.
The other day I parked it and noticed an odd smell, when I popped the hood smoke was coming from the plastic tubing that holds the positive cable going to the battery and negative cable that goes to the block. I unhooked the battery inspected the rest of the wiring for any insulation that may of melted off, and noticed no other problems. I replaced the battery cables and when I tried to start it, it turned over, but I have no spark. One of the relays clicks back and forth really fast when I first turn the key on to the position where the fuel pump turns on. Ive checked the three fusible links coming off the power distributor, the cam position sensor, checked and replaced the crank position sensor, checked the coil, and the distributor. Could my ECU be fried?
When I first bought the beautiful blue beast I call my jeep the guy told me that one time when he jump started it the stock radio quit working and the AC compressor stopped kicking on. The guy didn't seem very mechanically inclined, so assumed it was just some fuses. It turned out not to be and I never could figure it out. Could these issues also be related to my ECU? I replaced the stock radio with an after market one and havn't had any problems with it blowing fuses or anything.
