The fuel pump relay on a Saab 900 is designed to regulate power to the fuel pump. When the ignition is turned to the "ON" position the power train control module energises the fuel pump relay causing its internal circuitry to close. When the relay's circuitry is closed it provides power to the fuel pump. As this relay ages, its internal circuitry wears out and can malfunction. A malfunctioning fuel pump relay can render the fuel pump inoperable, preventing the engine from starting. Replacement fuel pump relays are available from auto parts stores and certified Saab dealerships.
