I have a 2001 Silverado and it does not want to start when it rains, but when the weather is nice it cranks with no problem? Tempermental truck? Female truck? What could possibly make this happen?? I am more of an old truck guy than a new truck guy so the electrical gremlins seem to get me frustrated. Here is my 67 that I built....eer....am building. Any help with my (newer Chevy) would be appreciated!!!!!

 

check for codes...

 

auto zone will check the codes for free

 

check ign. coil

 

I checked and cleared PO102 (cam shaft posistion sensor) and PO341 (MAF Sensor). The only code that came back was the PO102. I changed the distributer cap, and the pick up coil, otherwise known as the cam shaft posistion sensor, cleared the codes once more and went for a drive. No check engine light and the truck started with no problem. The weather was foggy, damp and 55 degrees. This is the problem weather so it was an excellent test day. Thanks for everyones responses and I hope this helps someone else!
