Hey everyone! It's been awhile since I've been on... busy as you wouldn't believe (I'll explain later if anyone cares). Anyway, I'm having issues with the ignition system. Here's the rundown: 1999 Cherokee Sport, I-6 motor, AT.
I was driving back to the office from a delivery when I started to feel a loss of momentum. I quickly looked down at my gauges and for a moment they were still reading normal. I couple of seconds later they all dropped. I coasted to a stop on the side of the road and turned off the ignition. I waited for a second or two and tried to turn the key over. Nothing. Not a single guage moved - Volts didn't show, Temp didn't move from 0, and the gas was sitting at E.
I had it towed home and started looking through the engine compartment and found that the idiots before me spliced the Green/Orange wire that runs to the coil, alternator and fuel injectors to the battery. I replaced the brain (used) and fixed the issue with the guages, but the Jeep still won't fire.
I next hooked up my inline spark check tool from the coil to the center of the distributor cap and cranked the engine. Once more, nothing. I bought a new coil, but before installing it I checked the old one with an ohm-meter and followed the instructions in my Haynes manual. BOTH coils tested the same. Here's where I would like some advice....
Since both coils tested the same, that leads me to believe that 1) my original coil is fine, or 2) both coils are bad. My question is the pick-up coil in the distributor the cause for my ignition coil not firing? Is there an inline fuse on that particulare wire that I just can't find?
Oh, when I hooked up my multimeter to one of the connectors and cranked the engine, it read 0.5 volts coming from the computer to the ignition coil - is that right???? Thanks so much everyone!
