Normal fuel pressure should be 55-65 psi at idle.

SOURCE: in-the-tank fuel pump r&r
Here are instructions for replacment with a diagram of the fuel pump components my only suggestion would be instead of draining the tank and dropping the fuel tank if you unbolt the box and using a jack and and some wood lift the fuel tank side of the box this will give you access to the tank and fuel pump/ sending unit. It will save you time and the hastle of replacing the tank straps which are prone to snapping at the threads when trying to remove the nuts.If these brake you will have to replace them.

You said you have fuel pressure but what is it? It has to be 55 psi or it won't even try.
SOURCE: LOW OIL PRESSURE ON 2007 GMC SIERRA 1500. CHANGED
have it tested using a manual gage if still low then main baring ore most likely bad that would mean a over hall if is really low and bearings bad should be making rattle noise when started up first few seconds
Testimonial: "thanks alot.truck is not making a rattling noise.we did check it with a manual gauge.it read about 10 at idol. press. gets better as you incr speed"
