Re: headlites go off and on on a 88 cherokee
Sounds like you have a bad relay. The headlight relay is located by the fuse block. You will hear it click on and off as this problem occurs. When you think you have found the correct relay it will more than likely be hot to the touch indication it is bad.

You may have a problem with the fuel delivery being a fuel pump that's going bad or a restricted fuel filter that can't keep up with volume of fuel needed to keep your vehicle running. I'd start by having your fuel pressure tested
Your ecu is going bad. The power caps in the ecu are old and weak, needing time to build up current enough to supply the ignition and fuel systems. Only then will the check engine light illuminate and the vehicle start. You can either have the ecu replaced or the caps within it repaired

That happen to me 3 days ago. The problem is on the ignition key. When you turn it to start the engine, once the engine starts, turn it back a little. is suppose to get back by itself but, get stuck because the cold weather.

If that is carbureted, and has a mechanical fuel pump, try running a length of fuel line from inlet side of pump to a gas can that has fresh, clean fuel, and if it runs good that way, you know problem is most likely in the tank. Removing the tank & cleaning it out is best solution from there. I'd even be tempted to add a small bottle or 2 of Lucas Fuel Sytem Cleaner to first fill in clean tank, just to help clean lines as well as carb.
