1992 MITSU DIAMANTE 3.OL DOHC. CRANKS BUT NO-START. FUEL PUMP DOES NOT RUN WHEN KEY TURNED ON OR START POSITION. WHEN TURNING KEY TO "BUMP" THE MOTOR AND LETTING OFF THE FUEL PUMP WORKS FOR ABOUT 3 SECONDS. ANY IDEAS? IS THERE A COMMON ISSUE? MOST CARS I HAVE WORKED ON WHEN YOU JUST TURN THE KEY ON THE FUEL PUMP PRIMES FOR ABOUT 3 SECONDS BEFORE STARTING.
