Exsessive cranking, runs great when running.No codes. Does not build fuel pressure right away.Has good pressure while running. Leaks down immediatly. New pump, regulator, filter,and TPS. How can I check for a stuck injector,or can it be a no code computer or sensor problem? Can you help please!!

YOU NEED TO INSTALL A FUEL PRESSURE GAUGE AND START BY CRIMPING THE RETURN LINE AND SEE IF IT STILL LEAKS DOWN. IF IT DOES YOU ELIMINATE THE REGULATOR. THEN WHEN THE PUMP SHUTS OFF CRIMP THE FEED LINE TO THE INJECTOR, IF IT STILL LEAKS DOWN THEN YOUR PROBLEM IS THE INJECTOR. IF IT HOLDS THEN YOUR PROBLEM IS IN THE FUEL TANK. HOPE THIS HELPS. FEEDBACK IS GREATLY APPRECIATED.
