headlights burned out. Relays were suspected, found one that looked burned out. Replaced it, no dice. High beams went out. Replaced the other relay. Still nothing. Just replaced the fuses, and bulbs. Still nothing.
Must be that damn switch right? The thing I wanted to avoid fixing by upgrading my harness, ha ha.

So someone on the internet with a 2000 XJ said they replaced the CPS, got a misfire, threw code for ignition coil, replaced with JY unit, really bad misfire with flames out the vac inlets on manifold.. Thoughts? (Here's the link)https://www.reddit.com/r/CherokeeXJ/...GP&sh=8f19506e

After that, it's just a matter of checking the relays, which many have reported that the relays that come with the PUTCO harness don't last long at all (not sure which harness you went with). I've been fortunate enough with mine, I put mine in about 4 or 5 years ago and they're still working fine.
1990 Cherokee Laredo 4.0. Need help!!! Im new to jeeps and no mechanic. I bought it a while back, ran ok. Then is started to miss, so i replace cap, rotor, plugs, and wires... Same issue. So i replace fuel filter, same result. Fuel pump thinking maybe it sucked up some sediment from tank. Still missing!!! So i go to the local mechanic shop seeking advice. He tells me injectors, so i pull the injectors, blow them out, problem solved.... So i thought, after buying new injectors and installing them jeep rund good for a couple days, now it wont start. Replaced the distrubtor tonight and it still wont start. I need some advice, please.

Do you have 12V on the original headlight connector when you switch the headlights on?
Transfer
I need to know if I can use 4.0 HO out of a 91 Cherokee going into a 97 grand Cherokee Laredo? I am pretty sure the blocks are the same, but that is about the extent of my knowledge.
