Fuel Shutoff Solenoids

Starting Motor Solenoids

Fuel Shutoff Solenoids -

Fuel shut-off solenoids often are used on diesel engines to interrupt fuel flow from the injection fuel pump when the ignition is switched off. On start-up of the engine, a solenoid pull-in coil must be temporarily activated to turn on the solenoid. If the key is held at the start period for an extended period of time or if the key sticks in the start position, the solenoid will overheat and can burn out and fail.
