Fueled day before driven 25 miles, died Checked fuses all good, replaced relay for fuel pump. Power to FP and ECU Fuses while cranking only. What to check next? Thanks
Died on road, No start, no power to Fuel pump fuse or ECU fuses Relay new on 2001 Volkswagen Passat
It is normal to only have power to the fuel pump when cranking, because you HAVE to have an rpm signal for the ECU to energize the fuel pump relay. This is safety feature on just about any car. Try spraying some carb cleaner into your engine and see if the engine runs a bit. IF IT DOES, then you have no fuel delivery, yet you have power to the fuel pump, therefore the fuel pump is defective.
