Check fuel pressure at fuel rail. Even if pump is working does not mean that its pumping good enough to give you the fuel pressure you need.

Should be 50 to 55 psi on rail

Yes pump for sure. Haven't been around a fuel pump change on a small truck yet. It is a pain on the 1/2 tons. Advise. Hose all gravel off of the top of the tank. Take the driveshaft out. Usually a weak pump can still move fuel it just cannot build pressure. I take the filter out and slip on a hose and let the pump drain the tank into a pail. Makes the tank alot easier to handle. 2000 should have the quickconnect fuel lines you'll need the cheap separation tools.
