Well, it's kind of an odd coincidence that it stopped running again. I would say it's probably something to do with the previous repair. If you bought an aftermarket fuel pump, I'd say for sure it probably went out..you get what you pay for. You really need to use GM parts.

I'd recommend rechecking your work, maybe a line or wire got pinched under there when the tank went back up into position, or maybe the pump's electrical connector came disconnected. Hard to say, but I would concentrate in the area you just worked on. A quick fuel pressure check would tell you if the pump went out or not.
