Are you sure the fuel pump hasn't failed? When you first turn the key on, do you hear the pump prime for approximately 2 seconds?
Also, there is an inline fuel filter between the tank and engine. It is mounted on the passenger's side frame rail. See pic 1 below. Has that been checked or replaced?
Let me know.
