The Pump-Prime feature automatically runs the fuel pump for up to 3 seconds when the ignition is switched to the "On" position. This builds optimum fuel pressure before cranking the engine, insuring your Porsche starts as fast and as smooth as it possibly can.
“Diagnostics”
This optional feature allows you to instantly know the state of the DME Relay. It features four LEDs that are directly connected to the critical inputs and outputs of the relay. All four LEDs must be illuminated for the engine to start and run. If one or more LED(s) are off , there is an issue with the corresponding circuit.

Ctl. Fuel Pump – (Blue) Input signal indicating the DME has commanded the fuel pump on.
