RE: 3.3L Engine. Stalling when damp or raining out.
Sorry Mods/Admins/Members, I had to make a new post about this, because the last one would not let me reply to it. Just kept getting an error.
BillRon Replied this with.
I have since been to the wreckers, got a next to new DIS Module. I replaced it, yet the stalling continued. And only when it is on wet roads. It's almost as if the gas flow is being interupted. Could it be the wiring to my fule pump/sending unit that is shorting when wet and stopping gas flow?
Thank's for your reply BillRon
Any more help with this would be greatly appreciated.

I recently purchased a 1995 Dodge Caravan. 3.3L engine.When it rains out or is damp outside, the engine will stall. I still have power to everything but the power-steering. It's easy enough to pop it in neutral and start it then back to drive, but also seems pretty dangerous when on the highway. There is no distributor rotar or cap, the spark to the plugs is generated from a rectangle box on the side of the engine. It was mentioned to me that it could be the module in this box, or the coil. The plugs and wiring are brand new. I also noticed when I spray the box with a water displacer meant for wiring, it will not act up as much when damp out. Could somebody tell me the name of this box, and the components that are contained inside. As it is, I was led to believe that there is a coil and module inside this box.
Thanks for taking the time to read and possibly help me!

That is your DIS module (distributorless ignition system) It works as though each of your spark wires has its own coil. You can google it to learn more about it. I believe some have a seal on the bottom that may go bad. Usually it is packed with a hardened silicone. Make sure it didn't crack and pull your wires off and spray a water displacer in the connectors. Hairspray works well if you have used your other up.

RE: 3.3L Engine. Stalling when damp or raining out.
I would be very suspicous of one of the plug wire boots not being on all the way on since you say they are new. I would also check to make sure my connector to the DIS mod is not cracked. If those prove ok check make sure the fuel relay isn't cracked. If your problem is in deed moisture any part of a defectiveignition systemmay be faultingwhen moisture gets in it. Also be leary of vaccum leaks. I am not a dodge mechanic. Iwas a diesel mechanic for many years who has very limited time to work on my caravan but I do all of the work on it I have had to come to this site for questions. Actually its my wife's van and is often a part of my "honey do" list.

Thanks for the input. I will check the relays, and I will check the DIS connector. I will definately check the plug boots as well. I'm gonna have to get underneat and go along the fuel pump wiring, just to be sure it's not exposed anywhere.
Thanks again for your time and knowledge!
I'll report back.

How did you determin cam sensor? Be carful about replacing sensors based on a code. Codes tell you that something in that system was out of range not that the component is bad. Also it is easy to get an eroniuse code in the event of an engine stall. Have you replaced it and all is good now?
Owners manual will indicate the intervale for fuel filter replacement in the maintenance schedule. As a general rule 30K miles should work but some manufacturers recomend more frequint.

RE: 3.3L Engine. Stalling when damp or raining out.
Well the Van is 13 years old, and I'm only the third owner... I don't think it's ever been replaced. How I came to the conclusion that it is a cam sensor, is I sprayed it down with a water displacer/sealer, and drove through some gnarly puddles, not one stall. That sealer wont last forever. Any suggestions on sealing it permanitaly? Or should I just go ahead and replace it.?
Thanks a ton for all your help and advice. Greatly appreciated.
