All STINGER 4 ECUs can control a fuel pump via one of the auxiliary outputs. All outputs can be programmed to function in various ways for controlling different devices. One way is to control a fuel pump. In this mode the ECU will turn on the fuel pump instantly when the ignition is turned on. If there is no attempt to start the engine then the pump will turn off again after 4 seconds. As long as the ECU detects a continuous trigger pulse from the engine it will keep the fuel pump on. Once the engine stops turning then the fuel pump will be turned off after 4 seconds.
