Hi all,
I don't post here much, but follow the forum and value your opinions.

Here's the problem: Once every month or so, the starter does not turn at all when attemting to start the truck. When it does not start, it may not turn over at all for 10-20 turns of the key, then all of a sudden, it starts right up.
I have replaced the starter, and cleaned and tightened all battery connections. This problem happens when cold and fully warm. The starter never cranks slowly, its either a perfect start or nothing at all.
Is there a relay or something I can check in between the switch and starter that may be the problem? Maybe a relay or ?

Thanks for the help.
