russ6570 Posted December 26, 2009 Share Posted December 26, 2009 I have a 1987 jeep Comanche, 4.0, 5 speed 4x4, absolutely base model. I recently replaced both the starter and the battery, and then it just didn't start one day. After I had already driven it that day. At first I thought that it was a weird issue with the wiring for the amplifier I had put in that day, but after I removed all that, it still didn't start. All my lights work, and my over cab lights work, those get are connected to the fuseblock via the open space labeled IGN. My voltmeter in the truck reads at the halfway mark between "9" and "14" (newer style gauge) when I try to start it. And yea, that's about it. I don't even know where to start with diagnosing it. Could someone please help? Link to comment Share on other sites More sharing options...

JeepcoMJ Posted December 26, 2009 Share Posted December 26, 2009 Sorry, I forgot to mention, it doesn't crank. did you wire the amp supply wire to your starter relay(little box where all the power wires go to...the thin + wire from the battery goes to it)? you probably just arc'd the starter relay and fried it. cheap part, and it controls ignition power to the starter solenoid.

russ6570 Posted December 27, 2009 Author Share Posted December 27, 2009 Thanks! I wired it directly to the battery, but that's about the only thing that I have to work with. Thanks! Link to comment Share on other sites More sharing options...
