My 2000 GMC 2500 with 350 V8 won't start when it is rainy so I replaced the spark plug wires. But the problem persists. Any suggestions?
GMC 350 V8 won't start in rain

Oh, I forgot to mention, there are no codes.
If it has distributor cap and rotor, ck to see if moisture is getting in there. Be sure no a/c lines are close enough to drip moisture on the cap.
Get a BIIIG umbrella!

They had a TSB on that. In the TSB water would leak past the seal where the hood meets the cowl and drip right onto the cap.
How would I go about finding the TSB?
I saw it in one of the mags we get at the shop. I'd try covering the distributer and coil with plastic too see if it fixes it.
Good suggestion; I'll give that a try. Thanks, Chris.
I think the TSB is for v-6's only. But I'd still check.
I would get a can of wire dry and when it rains spray small sections of the wiring until you find the problem. I assume you replaced the coil wire if it has one? If it will not start, that means its something common to all cylinders, not just a wire or two.
