Sometimes a fuel pump doesn't build pressure and all of the pressure has bled off from the last time you tried to start it. Try this: turn on the key but don't try the starter until you give the fuel pump a couple seconds to run with the engine off. Maybe 3 or 4 seconds. Then try the starter. That often solves the problem as vehicles get older. Yea, it's an annoyance but it beats messing with pressure relief valves and replacing a fuel pump that is perfectly ok except for a possible back-pressure leak when it's off.
