There is a fuel pump driver module in the trunk, on the drivers side. Looks like a small brick, half black and half silver colored. You have to check for power coming out of the module to the fuel pump.
These modules are prone to failure. In the occasions I've seen these fail it was after the car had been sitting for a while. It may be pure coincidence, I have no idea. I do know that a lot of the issue is the lack of relay for the module and it's not uncommon to find an aftermarket relay added in to cure the failures.
