Answer
You need to release all of the built up air in your fuel lines first of all Jeremy by finding the fuel pressure relief valve on the fuel railing. Then depress it using a small screwdriver. then when all is relieved. fill it up with gas and allow the pump to run about 2 or 3 cycles and then try starting it. ALthough the pump could be fried as fuel is what cools these fuel pump's nowadays, So the voltage on the fuel pump needs to be checked as well.
