99 Sub. 7.4 C2500 hard rain then no start

I have a major problem. After the last three hard rains, my truck won't start for several days, then it starts and runs fine with no codes like nothing ever happened. PLEASE HELP.

What does the rain have to do with it? how high did it rise? did you have the hood up when it rained?

I have no idea what the rain has to do with it, but it only happens after the rain. it rained last night and today it won't start. It just turns over and there is fire at the plug.

Problems like this are almost always associated with the high voltage side of your ignition system. Replacing the dist cap, rotor, and spark plug wires should solve the problem.

Distributor cap..... might as well replace the rotor button too. Plug wires may be crappy too.
