88 Jeep cherokee/wagoneer problem keeping it running

I have a new (used) 88 wagoneer (cherokee style)

Finally got all the must fix fixes fixed and its running. alas not for long :-)

every now and then over the last week when I would start it it would start right up and then shut off as soon as I release the key. Did not think much of it as a restart worked fine.

now its dead. it will start up fine (and even KEEP running if I keep the key turned longer) but the moment I release that key to normal on running position it shuts right off.

on my other jeep cherokee (same year) some fuseable links were bad running to that metal box right behind the battery. I gave up cut it all out and installed a fuse box and soldered it all up. no more problem.

but on the new truck I tested (by bypassing) each fuseable link. no joy.

could the box they connect to be the problem ? (some sort of relay) it clicks when I start the car. its only $15 so in a ffew minutes I am going to go get it and put it in. but I wanted to post here first in case it fails then I might already have some replies :-)

What else could cause this problem. starts right up and then off once you release the key.

clearly the electricity to the engine is being cut off (at least that is what I am assuming)

this is what would happen if a pulled one of the installed fuses on my other truck. without one of the fuse it would start but stop once you release the key.

what else could do this ?

Thanks Chris Taylor

Chris You didn't specify which engine you have, but since you said it's an 88, I am assuming it's an AMC 360. One of the first things I would suggest (if you haven't done it already) is to call D/C publications and order the factory service manual for your year. It's the best $60 or so that you can spend.

for some of the best information re: your full size jeep. 2) it sounds like the resistor wire is broken. The starter solenoid bypasses the resistor wire in order to supply full voltage to the coil during starting. As soon as you release the key, the bypass contacts on the solenoid (relay) drop out and the resistor wire drops the coil voltage to it's normal operating voltage. (If it's not the resistor wire, it could be the ignition switch not making contact in the "run" position.) I would start by putting the ignition switch in the "run" position and testing the voltage on the "+" contact of the coil. You should have about 6V DC with the engine not running. I would also recommend performing the TFI ignition upgrade. It provides a much stronger and more reliable spark than the old AMC ignition system. Go to

and search the message board for "TFI". You might also want to take a look at

Good luck with your '88. TJim 98 TJ SE 90 SJ GW

It really sounds like the little Cherokee style (XJ) with either a 4.0 or

2.5 engine. It also sounds like the ignition switch should be inspected if it dies as soon as you release the key. It might also be the fuel pump ballast resistor, but it should run for a few seconds and then die.
