  1. compression test. 2 pressure test using a fitting in plug hole with air compressor attachment welded to it. check that the valves that you are checking on each cylinder are in the fully closed position listen for air escaping into the exhaust manifold then do the same for the inlet side hope this is of some help

SOURCE: Jeep wrangler Fuse box

i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

SOURCE: 4wd problem jeep wrangler yj 1995

i just bought a used 97 CHEROKEE but i had the same problem, when i got to looking at it i found out the front driveshaft was shot, look at that, if its not it i would say its probably the transfer case especially with an older vehicle like that which is a very expenxive repair

You have two locations for the fuse box. One is either under the hood or behind the glove box. I would pull apart the glove box and take a look.

SOURCE: caster adjustment for 1990 jeep yj wrangler

caster is adjusted at the rear of the lower control arms. Camber is fixed and cannot be adjusted by normal means (though special off-set ball joints are available to do that) Toe in is adjusted by turning the sleeves in or out on the tie rod ends. None of this should be done at home though crude adjustments can be made in order to get the front end reasonably straight. Adjustments are made on an alignment machine that allows precise adjustments to all you mentioned as well as front/rear tracking.

Soft top-1993 Jeep Wrangler YJ


OK I have a yj and you start from the windshield put the snaps/or what ever yours is on the top of the doors then down the side or the doors then under the back side window then around the curve and this is the hardest part then your tailgate also make sure your bars on the inside are loseuntil the top is on then thighting those bars and you should have a nice tight top but belive me it is hard and you might need a flathead screw driver for the corners. Good luck and a jeep wave to you!

What type of transmission do i have?


Your Wrangler is a YJ and the model is an "S". A Wrangler manufactured in 1987 through 1995 are all YJ's and then from 1997 through 2006 are all TJ's. The new Wrangler models are dubbed JK's.

95 jeep yj wont start


have you checked the fuel pump ? the fuel pump is in the fuel tank and it may be that the fuel guage inside the tank is broken and or not attached to the pump. This is a big job but with a little help from buddys and a bit patients it can be repaired.
