Other morning went to start the truck and I got a really bad starter grind so I immediatly shut the key off. Tried again and got the same thing. On the third try it finally engaged, but the truck just started real quick then died. Did this about 5 times and finally I started it like an old carburated gasser, pumping the peda lightlyl and it started fine and hasn't done it since? Any ideas? How am I goin to get the stealer to replace the starter if thats the prob only so often?
