2000 Ford F150 6cyl won't start when it rains?

Asked by May 04, 2017 at 12:06 PM about the 2000 Ford F-150 XL LB

Question type: Maintenance & Repair

Just bought it - ran great. I washed it at a car wash. It wouldn't start for about
an hour. It would crank but not turn over. I didn't get the engine wet - just
washed the outside. Ran great after that (it was dry). It rained last night and
same thing. Truck will crank but not start. What gives? Please help! Thanks.

I would check the ECU connections for moisture and also check the spark plugs wires and the coil pack connections for moisture. Use dielectric grease to seal out moisture.
