Does not want to start!

You’re gonna have to expound on that a bit

 

She sounds like she wants to start but doesn't turn over.

 

Pretty much no change since changing out the timing belt, I had the marks lined up, turned it manually a few times didn't feel any resistance or crunching.

 

Let’s clarify terminology here. Turns over means when you turn the key the engine rotates. Now, due to the super sketchy belt and possibility of damage done, prior to trying to start it, did you do a compression test?

 

No compression test. Guess I should give that a try next.

 

Stop everything.

If the engine cranks, get starter fluid (ether) from the store if you don’t have a can already.

Spray a 2-3 second shot into the throttle body, just behind the throttle plate. Crank the truck. Does it catch and fire?

If not, your problem is likely with lack of spark. Test to confirm spark ASAP. If it does fire up, you have a fuel delivery issue, which could be caused by a number of things, but you just eliminated about a dozen possible issues with that one basic test. We need to know which one of the two it is in order to help further.

Note: “fuel delivery issue” DOES NOT mean “go change the fuel pump”. I want to be clear on that. A bad crank position sensor or its harness being damaged can cause no-fuel situation also. But confirm with starting fluid first, and let’s move forward.
