We have a 2007 Ford F-150 with a 5.4 this week it has happened twice after overnight rains that the truck will not start. After sitting all day in the sun we get home and it starts right up. If you have any suggestions please let us know. Thank you! And thanks for the add to your forum.

I had a probable just like that where the engine coil on my 4.2l had a crack and when it rained it got water on the coil and it wouldn't start. Idk if that would help with your truck since y'all have the separate coils.

Most likely your Fuel Pump Driver Module. It's located above the spare tire. After time they corrode and once it gets wet it doesn't work until it's dried out. Drop your spare and check it out.
