Hello, i have been having a problem starting, at first I would start the truck and it would be fine, but there would be this grinding type noise which I believe was the starter which didn't stop starting! I would then shut it off and try again, never to have the problem for a few weeks. However, recently I have gone to start the truck, but turning the key just turns the engine very weakly, almost as if the battery was dead! Trying again would allow the engine start just fine. What could be wrong? I want to fix this while it is still intermittent.
