I've researched this forum and can't find a concrete solution to my problem. I have a 1999 Dakota 2wd with the 3.9 V6 Magnum.
My issue is when it's cold and wet the engine will crank and not start. It'll start just fine when it's dry outside. I've replaced the plugs, wires, distributor cap and rotor. Have not replaced the coil yet, that's next.
I use to have a 2001 Ram with the same motor and had the same issues. My questions are, is this a problem that all Dodge trucks have or is it just that particular motor and how do I correct it?


Thanks for any and all help

sounds like moisture getting where it shouldn't. try spraying wd 40 in the cap and see if it helps (only wd40 not another brand) might be a connector also, it's just going to be check everything until something works (basically like wiring) I think

 

I'll try the WD-40


Thanks

 

I've checked this before by just waiting for a cold wet night, then popping the hood and have someone crank the engine. Watch and listen for sparks under the hood.

 

I had same issue on my recently aquired Dakota. Reading through different threads instead of trouble shooting the issue I threw money at it. I replaced wires, distributor cap & rotor, coil knowing it hadn't been done. For me that solved my issue it runs so much better and cranks over in the rain. Sounds like you've replaced the same things maybe your issue lies with that coil. I know I read other posts mentioning it.

 

Besides replacing the coil, I would check and clean all of the engine ground wires.

 

Checked for any loose ones, didn't think to go ahead and clean them as well.
Great idea


Thanks

Wanted to thank everyone for their tips.
I was finally able to replace the ignition coil on Monday.
It's been wet and cold here the last couple of days, and she's been starting fine.
Now on to a little body work that needs done soon.

i find that plugging the vent in the cap works to solve that trouble. i use JB-weld
