Sounds like you have run afoul of the dreaded PassLock security system --- deals with the problem that GM engineered a security system that sometimes, with age, mis-interprets (doesn't "see") your ignition key in the ignition and assumes that the car is being stolen and shuts down the fuel pump. You will hear the pump run for a moment to engergize the system but then it just cranks and cranks and cranks. Do a search on Passlock and there are work-arounds to fixing this permanently --- temporary fix? Read your owners manual about re-setting the security system (sorry I don't recall it exactly) but it deals with turning the ignition key on/off in a sequence and then leaving the ignition key "on" for 10 minutes or so. Three daughters, all with Grand Am's, all had this problem. And it sucks when you are sitting in a mall parking lot in the rain waiting the 10 minutes for the system to re-set. Evenutally, the ignition key situation will worsen until it permantently will not re-start.

Good luck.

It is unnecessary to bleed the lines after installing a new fuel pump. The fuel pump will pump all the air out of the fuel lines and start to work properly without any bleeding. Just install a new fuel pump and start the engine.
