I dropped the gas tank to check the fuel pump. Garage that installed it 7 years ago said they installed new, however I can tell you that looking by the "electrical that was on it" it was not new. Really not the point. The fuel pump seems to be working fine. Dropped in back in and reinstalled and connected all points. Truck fired up idled for 5 minutes then stalled. Now no pressure in fuel rail but I can hear the pump kicking on and off... Any suggestions?
