Fried Wire runs to o2 sensor. Just had to keep looking.

Found it!!!!! In the mix of banging and wiggling things while the truck was running I saw a arc flash near the the top of the manifold. Sure enough there is a black wire feeding the injectors, I believe this it what the wire is doing, that is completely fried. Arcing out on manifold. Checked...

just a bit worried that a bad o2 sensor fried my PCM, but if it was the PCM I don't think It would run like new when it is running. I'm gonna go bang and wiggle things around.

believe i might have bad relays in there. Got jeep to run today. Fuse blew again when i hit a speed bump at faster than normal speeds.

1996 grand cherokee ltd. Have been told it is fuse #20.

toaday i checked the o2 sensors. Wires looked ok, but I unplugged them both anyway, replaced fuse, and turned key. The Relays went crazy for a few seconds then settled. Problem went away. So I ran a on board diagnostic test and came up with 12 and 55. Jeep started. Took it for a test drive, all...

I'll give it a try after work and let you know. Thanks again for helping.

Any one no what this fuse controles? Blows everytime i turn the key on. Engine wont run, but turns over.

Thanks. I appreciate your help.

I uploaded a picture of the 20 amp fuse witch blows when i turn the key to run position. I'm having a hard time finding out what it is for. Can anyone help me out with this?

I have a 96 grand cherokee 4.0 that will crank but not start. With key in run position i get no fuel gauge, volt gauge, and no check engine light. The red light on the dash turns on solid, and the on board diagnostics test does not work at all. A 20 amp mini fuse under the hood blows as soon as...

have fixed this problem. Fixed and checked all grounds, replaced battery, since it was still on warranty, and cleaned and tightened all electrical connections on starter, and alternator. Problem has gone away. I believe it was bad cells within battery.

my 96 grand cherokee limited is having some electrical issues. While driving the speedo jumps up all over the place, the voltage gauge drops completely, and looses considerable power. If i turn of jeep and start again it magically goes away for a bit. Also i can here static in stereo speakers...

Re: Oil Leak Problem NEED HELP? these oil leaks are a pain but easily fixed. Change pressure sending sensor, 0-ring in the oil filter adapter, oil pan gasket (make sure oil pan bolts are tight and not the cause of leaks.). Have heard that the dipstick can leak at the block as well. If you're...
