Can you hear the pump run when voltage is applied?
Are you sure that there is fuel in the tank?
Where are you checking for fuel flow when the pump is running?
Are you sure that the new pump was correctly installed?

what engine/transmission

no start in neutral- may just be adjustment.. wiggle shifter in neutral and see if it'll crank..

as for above poster said also check to be sure its hooked up to the right line and not the vent or return line..
