Ok here's one either my truck is haunted by my dad or hes trying to tell me something. Changed the serpentine belt now truck is harder to crank over and the door locks while cranking ........anyone ever seen this before or heard of it?
LOL. yes, that would be a battery issue
Surprised it even turns over, you are in the "click, click, click" voltage area
Question: How long has the truck been sitting? Reason I ask is that there are some accessories (ECU, radio) that draw power even while the truck isn't running. I've seen my own vehicles sit more than a month, and then the battery is dead, or near dead, but once it's charged up again, it's fine.
Before you replace the battery, try charging it.
Oh, one other thing: I see you're in New Jersey (your zip code). I'm pretty sure it freezes there, and stays frozen, for a couple of months in the winter. If the truck has been sitting over the winter with a dead battery, the battery froze, and it's done.
One way to tell that it's been frozen is that the case bulges.
