Went to start the truck, turned the key dash lit up, fuel pump primed, turned the key all the way and nothing. Truck did not even try to turn over, headlights did not dim, no starter, no crank.
I checked/tested the following:
Battery and terminal connections good fully charged 12.3v
Ran battery charger on slow charge 10-15 min (quick) to full 13v
Wiring to starter good
Relay box under hood - has power
Starter relay has wiring diagram on it tested good.
Every ignition related fuse in the relay box all good
Every ignition fuse in the drivers side dash fuse box good
I wiggled the ignition switch while turning every possible way no crank
I ran the gearshift lever through all the gears, tried to start it in neutral no crank
Rolled the truck a little, put in park no crank
For some reason I decided to double check the # 24 RDO IGN fuse - it was fine. With the fuse still out I tried to start the truck and it STARTED!
I turned the truck off, replaced the fuse and the truck started again and, so far, ever since.
I do not think the # 24 fuse had anything to do with it; I just got lucky.
Can anyone think of anything else I should check?
