Not sure if you can help

[Imabur.]

I'm not sure of how many of you on here are great with vehicles.

I'm having a problem, and I've tried everything.

I have an '01 Jeep Grand Cherokee Laredo. The problem is:
I will turn my jeep to 'on' and none of the gauges will work, I can try to start the jeep, it will start for a few seconds and then the engine will cut itself off. I've already tried changing the cam sensor, that didn't do anything to help the cause.

Other related/unrelated problems (not sure if they are part of the main problem):
-Power windows wont work
-Door lock on the driver side only locks/unlocks the driver side, relay isn't running through the other doors.
-Overhead display with 'XXX Miles to empty' or 'Trip Miles' and temp outside, not working, just displays '----' on numbered varied items.
-Cruise control wont turn on.
-Interior lights wont turn on when I open the driver/passenger door, but will turn on if I open the back doors.

All problems started occurring with-in a week of each other which is why I'm not sure if they are all linked or just me having bad luck as usual.

I just want to see if anyone has any input on what the problem might be before I have it towed to fix it, because I'd rather not spend that kind of money right now, seeing that I don't have that much to begin with. I'm thinking it might be the crank shaft sensor, but that wouldn't affect the gauges at all (I don't think?). Someone said it might be the tac sensor, but I doubt that. It might just be a computer problem, and if it is, then there's pretty much nothing I can do.

Any suggestions?

Something with the battery? Maybe the alternator... I recently had to replace my alternator and fuel pump, not fun. When the alternator went bad it wouldn't even make a sound when I tried to start it, none of the electronics or light would work, and the battery wouldn't charge. Of course it is a 1994 Chevy S10 xD

This all started within the last week?

I'd say a bad ground. grounds can cause ALL kinds of problems.

I'm wondering if it isn't your computer??? It doesn't make sense that all that stuff doesn't work, but your car will turn on. If it were your battery it wouldn't turn on at all.

It could also explain why stuff slowly started going down hill rather than all at once. I had a 1990 Geo Tracker and everything electronic stopped working one by one-not that it had that many power things The computer was shot.

Reset the on-board computer. You can find out how to do that from google. See if that helps. If not, check all your fuses and battery.

too bad your dash lights don't work - anything like a cam sensor or O2 sensor should throw a code.

See if you can borrow a code reader from Autozone - most electrical/sensor problems will show up.

here's a question - do your hazards work?

It's not the alternator, I don't think it is the fuel pump just because when I turn the car to 'on' none of the gauges would work, and they should at least read fluid levels even if the fuel pump isn't working, I also own an '88 chevy s-10, love it. lol of course there's alot of work into it and turning it into a show truck.

That's what I thought, but I don't know a ground that would connect to all of these problems.

Ya I think it's the computer too, because I was just playing with it, and everything was working perfectly fine again, then started to drive it just to play around with it, everything started freaking out, gauges flipping out and all that good stuff.

I check all my fuses and relays, everything is fine. I already tried reseting the computer, I think the computer is shot.

The dash lights do work, but the sensor to turn them on when I open the door isn't working. Yes, the hazards work.


When I got it running, I took it straight to the dealership and left it overnight to wait for them to open tomorrow. I didn't want to wait till tomorrow morning and find out it wasn't going to start again. Thank you for all the advice guys =]

Let me tell you I had the EXACT same problem in my 2001 S-10 that WAS a show truck.

It was a ground on the main fuse box that went into the fender.

I then had the same problem even after fixing the ground, and it was water that had gotten up into the fuse box due to running no inner fenders.

Never the less, hope they get it straightened out for ya.

Ya, it was weird, because I had this problem a week ago, I messed around with the cam sensor and then it started working perfectly fine. Then someone smashed in my window, so I bought a new window and mirror (the mirror broke, too) from a junkyard and replaced it, so when the windows stopped working, I figured it was just a ground that got messed up when I put the door panel back on. Then this started happening again, and I figured it was the sensor again so I bought a new one completely to just fix it and get it over with, of course that wasn't what was wrong and still didn't work. The ground that goes into the inner fender from the fuse box...I install underglow (yes, underglow on a jeep =P) for fun, and ran the wires throught he inner fender right were the fuse box was, but that was about 6 weeks ago, so I don't think it would just start acting up that much later. But who knows. Hopefully they'll figure it out and fix it up for me. I guess that's what I get for buying a used car =\ ran perfect when I got it...for about a month, then everything started to go downhill.

the first thing I would check is the ignition key back( the electrical part of the ignition switch) second would be the multiplex control unit. You said that when you crank the jeep it will shut off instantly that is a classic sign of a key back.
