My car's fuel pressure will randomly drop from 35-40 to 0 while Im driving, if I let off the gas it will creep back up to around 30. Putting a heavy load on it usually makes the pressure drop to 0. replaced the fuel filter and the fuel rail pressure sensor. Did not think it was the fuel pump because it is an electric pump and it starts the car with no problems.

Either the pump is going bad or there is a loss of power to it.

Could the loss of power be due to the fuel pressure driver module?
