I have a 2001 f250 5.4 triton. My cb antenna hole leaked water in cab, soaked my fuse block. Horn goes on and off, radio turns on without key in ignition, truck only starts when key is on and I bridge solenoid, and number 4 coil is not firering. I have let truck dry out, fixed the leak. Everything is bad to normal except starting issue and coil issue. Any ideas?
As noted above, I would remove each fuse and use some very light emery cloth on the fuse pins itself if required and electrical contact cleaner spray with a dental pick if needed in the fuse block. Of course, remove power by disconnecting the battery before doing anything electrical in nature
