IT IS HARD TO START AND HAS A DEAD SPOT ON TAKE OFF, BUT NO PROBLEM WITH ACCELERATION OR RUNNING FLAT OUT. IS IT NORMAL FOR THE FUEL PUMP TO MAKE THE CLACKING SOUND WHEN THE KEY IS FIRST TURNED ON?
Your fuel pump suppose to Hum and gently vibrate only when working normally, clacking sound would only mean that it is having a hard time or inconsistently supplying gasoline into your engine. Have it checked and see if any improvement would happen.
