distributor cap?

I think we need more info. Does it turn over? Do you have hood vents? Does any water get inside the jeep?

Do you have a "FOR SALE" sign in the window?

My 89 floods when it rains too, but mostly just the cabin. I keep saying I'm going to swap-out the wing windows with later model that don't open.

It will crank all day it will flood with gas ive done almost all of cruiseres renix tips fixed the wiring it was doing it before i did a cap and rotor on it and after no hood vents hood stays closed all the time the windows are always down but it wasnt flodded with water in the cabin seat just a lil wet it was so cal rain noting heavy.

How old are the plug wires? This really screams weak ignition IMO.

x2. Check for spark?

Kris smith

I haven't check for spark. My plugs wires cap and rotor are all about 4 k miles on them right now.

hmmm. Check and make sure all your wire clips are engaged and boots seated over them, including the coil wire. I sure I saw someone asked earlier if the cap was seated properly, probably wouldn't hurt to check again.

An old school trick is while its dark and the engine is running (be mindful of the fan and belt!) spray the wires with water from a spray bottle, the subsequent engine stumble and/or arc is a dead give away when you've found the suspect.

Another old school technique to check the ignition is to tune the AM radio between stations and see if you can hear any arcing. If you hit the gas and the pitch changes in the radio, there is an issue. Cap and rotor are so weak in this design.

True. However, for reader with port fuel injection, injectors RF noise gets picked up too.

You can't ask for help until you check for spark.
