2004 Super Crew with 85k wont start when it rains or when there is a lot of moisture in the air. It shows no codes when this happens. Turns over fine and all accessories work just wont fire. we have tried everything, mechanic is at a loss. It first happen in a car wash and then started a couple min later, second time was also a car wash and had to let it sit in heated garage overnight to get it to start. Now all it takes is a rain shower... I Need My Truck Back.. Please any suggestions..

Check your Fuel Pump Driver Module. Its located under the spare tire. If you live up north and have salt on the roads, it tend to corrode and malfunction. If the car wash you went through had an undercarriage wash, then it might have gotten the water in there.

Had this exact problem with our old honda civic.

Turned out to be the spark plug wires; anytime there was moisture (rain) it just wouldn't start.
