Mazda3 Won't Start (Crank) After Driven In The Rain

This has happened 3 times now in the last couple of months. After driving on wet roads, our 2003 Mazda3 won’t start. It won’t even crank or turnover (primary vs. secondary ignition). All of the other electronics come on when you turn the key, but nothing from under the hood. After a while of presumably drying out… anywhere from 15 minutes to hours, it starts again. I’m thinking something is shorting, but no idea what. Any thoughts?

Mechanic can’t figure it out… but he’s only had it for a day, and it’s been dry, and starting fine. Thanks!

Try this.

The next time the engine won’t start, with the dash lights on, step on the brake pedal and shift the transmission into neutral and then try starting the engine.

If the engine starts, the transmission range switch is being effected by moisture.
