Just picked up a 92 xj, it was running fine till I parked it. The next day I greased the u joints and while I was under there fiddled with the two plugs going the transfer case but that is it. Also shifted it in and out of 4wd a few times to work in some oil to the linkages. Then went to start it and nothing. It wont turn over. The battery is good, all the guages, lights, etc. work but when you turn the key not even a sound. I cleaned the grounds, battery terminals, starter connections, cleaned the two plugs on the transfer case, tried jumping it to make sure it wasn't the battery and still nothing. Any ideas?

I'm going to say starter solenoid. When they go they go... There is no warning. You could check that there is voltage going to the solenoid with a meter while a buddy turns the key.

Happens to me sometimes. Step on the brake, shift it into neutral, then try starting.

Put a new starter in and its not the neutral safety switch. Cleaned another ground i had missed and still nothing.

this might be out in left field.....but....

CPS?

Ahh the elusive starting problem with our beloved Cherokees.

After a lot of experience with the CPS, I'd venture maybe that actually isn't it this time. When they go out, the engine will turn over (usually) but just not catch.

Not turning over at all... probably something other than the CPS

ahhhhh.....


ignition relay? in the fuse bos in engine compartment? swap out with AC relay etc etc see if that does anything......

just a thought!

im betting while you were messin with the two plugs you popped a fuse, i would check all your fuses, or if they werent pluged in and you pluged them in, unplug them and try it

here...did this writeup a while back. Guaranteed something on this list is the cause of your problems:

New symptoms if these help at all. Fuel pump kicks on for only a second or two then shuts off, and temp gauge spikes when i go to start it. Checked fuses and relay, not the problem. About to clean the nss but i doubt its that because moving the shifter around doesn't do anything and had no prior symptoms.

Gee oh Dee

Those aren't symptoms. Those normally happen when you turn the key to the ON position.

Do you hear a click at all when you try?

starter relay

ignition module on the steering column (i had the same exact problems with my 92 and this fixed it)

Probably your neutral safety switch.

Just curious, how did you check the NSS? Could it be possible that the plugs for the NSS (in the engine bay near the top of the firewall) may have come loose? Can you turn the key on and jumper the starter motor over and get it to run?

There's only a couple things that would prevent the engine from turing over and you're telling us you've checked all of them and they're okay. Might want to start checking them again.

Well what do you know, it was the nss. Guess it can go at any given moment because it was fine up until that day. Took it out, cleaned it and started right up. The nss was my first idea and should have went with my instinct and cleaned it in the first place. Thanks for all the help, owning two cherokees now I will at least know everything to check if I get starting problems again haha
