1994 Jeep Cherokee Sport 4.0 will be driving along and all electrical dies, car engine, lights everything. Coast to a stop, wait between 2-5 minutes and it will suddenly have power and you can start the car again.

It sounds like you do have a relay problem try switching relays around that have the same part number start with the starter relay when switching the make sure the key is off each time

Hi BigJoe,

Have you had any issues with your keys/ignition?

I have a Cherokee and a Wrangler. The Cherokee's ignition switch started getting flaky a while back. Sort of doing what you describe.

On mine, engine would die, dash lights out, like the ignition was turned off.

I'd give the tilt a bang and everything was back to normal. I got a replacement at a junk yard for $5.00.

The key symptom is, do the dash lights go out when the engine dies?

If not, disregard.

the check engine light comes on whenever a fault is detected in the electronic controls of the engine or emission system or the transmission, to find out what this fault is you need to have a OBD 2 fault code test run, there are over 200 possibilities here that can cause this ligfht to come on.

Sounds like a fuel problem??On the chasis rail back near the fuel tank there is a fuel filter that is often overlooked.Get that checked and I hope that is the only problem.If it is not.Come back to me and I may be able to help

I would try the crankshaft sensor. About the only thing left in the electrical department. These are known to heat up and fail. Also could be a weak fuel pump, but not as likely as you say it restarts immediately. You should have the fuel pressure checked before replacing it, as it's pretty expensive. ~ $175. I had one that would die intermittently, then it wouldn't restart until you got under the back and kicked the gas tank.

i would check your ignition system. you would need a meter for this but look for broke or loose connections. if it was a fuel problem i dont think it would just start up after 20 minutes. or you might try your ignition switch. if its shorting or something then ya well it would cut your engine off real quick

Put a new fuel filter on its pluged up. if that dosent fix it do a fuel pressure test.
