My F-150 with the 5.4 V 8 every time it rains or is damp in the mornings will not start engine doesn't even crank. As soon as it warms up and things seem to dry out it turns right over. I thought it maybe was the started so I cleaned the wires on the starter which were corrodid and put electric grease in them this didnt solve my problem. I was wondering if this is a common problem or if someone may be able to point me in the right direction. Thanks.
