To start off- Went to start the truck last night and she would not turn over at all. I thought it might have been the ignition cam, I just replaced it a couple of months ago with similar symptom. It was fine. I've had the cam position sensor go out on me but the truck will just crank and crank. Would a bad cam sensor not crank??

 

Do you have good batteries?

 

yep, put new ones in a week ago today.

 

what caused your batteries to go bad in the first place

 

6 years of use would be my guess. Finally had a chance to look at it and found a bad starter relay. The one mounted on the fender.
