My sons 2002 Intrepid wont start after it rains or it is real humid at night. I found a bare coil pack wire and a gound wire behind the coil pack bare for about 2 inches. I wrapped them in electrial tape. Do you think that could have been the problem ? He has had a new ignition switch and a couple other sensors replaced and still has the problem.

Probably a bad connection or corrosion at connections in wiring. I would start with the ignition system like a coil pack.

How to Test the COP Coils Chrysler 3 2L 3 5L Part

The above link has info on how to test the coil packs and primary voltage to the coil packs.

I would start by replacing plug wires then coil pack

possible fuel pump failure or coil -coil pack bad - or timing belt needs replaced

How old is the cap? Could the new one be bad? Also when it won't start do you see any sparks jumping from the coil or wires?

I have a problem with a 1999 Dodge Intrepid 2.7. Looking for some help or suggestions.

Problem: I only have a spark from the #2 coil.

Background:

Vehicle purchased from an Auction and would not start. The vehicle would only backfire. When I removed the valve covers I found that one of the rocker arms had popped out. I replace the heads with heads from a 2001 Intrepid 2.7. I used the cams, primary and secondary timing chains from the 1999 heads. Not sure if I used the original primary (left) cam sprocket from the 1999 or one I purchased in a kit from a Dodge dealership. I tried to use the new primary timing chain but it was not the same. The replacement heads were surfaced and a new head gasket was used. When I tried to start the vehicle it had no spark. The vehicle had set at several locations and parts may have been removed or changed.

Solutions Tried:

I tried 4 ASD relays with no effect. I then tested all 4 on a 2002 Intrepid 2.7 that runs and all worked. I then discovered that the Crank PS has missing. I replaced the Crank PS with one from a 2002 Intrepid 2.7 with no effect. I then replaced the Crank PS with a Crank PS from a 1999 Intrepid 2.7 and got a spark at the #2 coil only. I then replaced the PCM and TCM from the same 1999 Intrepid I got the Crank PS from and still only have spark from #2 coil. I then changed the Cam PS, still spark only from #2 coil. I have tried several coil packs on connector #2 and all have spark. Each coil pack that sparks on #2 will not spark on any other connector. Spark from #2 coil is weak.

I then replaced the wire harness from the PCM to the coils and fuel injectors and still only have spark from the #2 coil. What am I missing? Any suggestions, advice or related information will be greatly appreciated!

Thanks!

clean and spray all ignition plugs will busty penatration oil , check all body gounds for good contact , clean if signs of rust should help

its humidity that penetrates the iginition coil.check your wires,coil pack and spark plugs.have you changed them recently.it might be time for a tune up.

this vehicle has coil packs for the ignition correct? have you ran the engine at night with all surrounding lights outs so its really dark. spray a mist of water on the coil packs and spark plug wires to see if you have spark/voltage leaks jumping out from them. sometimes the tiny sparks will be so fine and skinny you can barely see them so it needs to be dark. hope this helps your trouble shooting. a coil pack could have such a fine crack for the voltage to leak from that you cant see it.

does the check engine flash while driving, a quick test, cause I suspect the coil pack, when dark open the hood start the truck and with a water bottle spray the coil pack if you see sparks replace it, change many of those here ....
