well, so far I've checked the fuses and relays in the fuse box by battery and then I checked all the fuses under the dash. Where do I need to look to see what I missed

 

Soooo, after much digging, I found this,my he yellow wire comes from the fuse block in the engine bay all the way to here under the dash. Looks like the PO spliced into it adding a relay and this weird plug that is screwed to the bottom of the dash where your knees are. Looks to me like the PO spliced into this yellow wire in order to get power for whatever that plug is for.



The yellow wire is cut and spliced into another wiring thing. Yellow is suppose to be the the wire going from the ignition switch to the fuse block for the starter relay





The yellow wires are spliced into a red and yellow wire that go into the wiring harness.





The wiring harness connects to this plug thing





The other side of the wiring harness plugs into this relay.

 

Oh, and forgot to say, does anybody know what that connector on he lower dash is for?

 

Some kinda aftermarket doodad

 

well whatever it is, it's all gone now, put the two yellow wires back together and jeep starts fine now. Only thing is that I can hear something rattling inside the catalytic converter. Time for a new one!

 

I found similary ****ery on my '99, although it's a manual. Someone had added in a box that pretended to be a kill switch/alarm junk, it made a little red LED flash like an alarm system would, and you needed to press the clutch AND brake to start. One day it gave up the ghost. Junk

 

I think I've seen one of those on the internet before. IIRC it was some sort of anti theft device. Is there a little card thingy you can pull out?

 

Yeah, I was thinking the same. Couldn't remember the brand name for the unit I was thinking of - had a couple thousand different combinations it could be, but it was a LITTLE more elaborate than that...

 

Now that I think about it, that yellow wire should be a good place to put a kill switch if one was needed.

 

May just need an oil pump. Sticky relief valve or worn out gerotor.

 

Hello I'm probably in the wrong place but this is all new to me. I have inherited my father's 1987 Jeep pick up it is in beautiful condition 87,000 original miles I have always driven a clutch this has a D with a circle around it is that overdrive? Do I drive it in 3? I live in mountain area I'm confused and don't want to ruin truck can you advise? Donna

 

Yes that's overdrive (4th). Don't worry about it. Just do your fluid changes regularly, keep up on maintenance. The AW4 is stout. If towing or hauling, a transmission cooler is invaluable.

 

true. Will check on next day that is warm enough. Minnesota's weather is spastic, to say the least

 

Glad you got it worked out man. If it ever happens again though, add MAP sensor to the things you should check. I was surprised to discover that this can cause a crank, no-start condition, but it can indeed.

 

very good to know. Thank u for sharing
