I'm having a brain fart on what year my truck is....I think its a 1999 2500. Anyway if I let it sit for a weekend and it's raining when I go to start it it will only turn over and not start. If I let it sit and the next day it's nice out it starts right up ....I thought it was the coil so I changed today in the rain but it still didn't start. The only other thing wrong with the truck is that the bolts broke where the exhaust meets up with the manifold so its not connected right now...could that be letting too much moisture in?

Thanks for any help

 

Distributor getting wet. You don't know what year your truck is?? Lol

 

too many vehicles....lol

you think its a problem with the cap? its not very old maybe 6 months

 

Go out there when it is relatively dark, open the hood, and have someone give the engine a crank. Do you see a light show? Hear a snapping noise?

How old are your plug wires? Distributor cap? Is the seal between the cowl, and the hood still there?

 

I'll try when I get home from work...thanks
wires and cap are appx 6 months old
also the cowl is still there
Thanks

just tried it...still not starting...no light show and no snapping

 

Sounds like a bad coil. Can you ohm it out? Specs are in the FSM.

 

replaced the coil while it was raining and it still didn't start but the next day when the rain stopped it started rigth up

 

Spray some water around in there with a squirt bottle, and see if you can get it to not start..... then find out where you are losing spark at.....

 

Were it mine, here's what I'd do next time it refuses to start: Pop the distributor cap off, wipe it out with a dry absorbent cloth paying particular attention to the area around the terminals, then spray a bit of WD-40 (specifically that, not a substitute) in there and wipe it around, again being careful to get it all around the terminals. Then wipe and spray the rotor the same way, and button it all back up. If it starts, or if the cloth comes out colored black or grey, replace the cap and rotor.
