Your not gonna believe this, I hit starter with hammer, nothing, put ohm meter on small wire on solenoid turned key to start, no power. I could hear the starter relay in fuse box clicking when key turned so I knew it was good. So I thought maybe the starter just quit, it went out about 8 yrs ago I was sitting in burger king drive through, switched truck off so they could hear me, went to start it and nothing, starter just went bad had to replace. Ok here is the part you wont believe, I decided to go through the mini fuses, trying anything before I took starter off to go have it tested, I found a 20 amp mini fuse that was for the dash power point/ cig lighter that was blown, I replaced it and starter fired right up. I kid you not.
