Bad starter? Bad alternator? Warped flexplate? Removing starter and alternator to have them tested. Gas is coming from the driver side valve cover air hose, when it does crank...

Ok first, what were you doing to the truck when this issue started?
Second why do you have a flex fan mounted backwards on that thing? That is a very good way to have alot of damage very quickly. Where is your clutch fan and fan shroud?
Also can you turn the engine by hand? For future reference, if the engine does not turn with the starter it not a good idea to just keep trying to force it.

The fan was on there when I bought the truck.
It turns over but just barely when it gets to a certain spot. I thought maybe the belt was bad so I took off the belt. But it still did that.

Also, I tested my battery and alternator, they're fine. Having trouble getting the little negative wire nut off the starter (what size is it?). Starting to look like a bad or failing starter...
