for a few days after it rains, car wash and even windshield wiper usage, I would hear a CLICK when I turn the key to start.

IF I keep trying or leave the key at KOEO it will eventually start.

what should I be looking for?

TIA.

 

I would check to make sure you don't have bad rubber covers on the two (in the EG it's two at least) wires that connect to your starter... water could somehow be getting to them.

 

I dont think it's your starter that's clicking. I have the same problem whenever i dont sufficiently tighten my grounds, it's the main relay clicking. Check and make sure all your grounds are tight.
