DI Function Stop Switch not cutting Fuel Pump output?


Recommended Posts

ECU is a G4+ Plugin for a Mazda MX5 running a Ford 302w V8 in my Mustang. (Don't ask)

At any rate, we have a DI configured as a Stop Switch, when active it kills the Ignition but the Aux5 Fuel Pump output remains hot, is there a setting somewhere that I'm missing?

The fuel pump in the MX5 is not normally controlled by the ECU, it originally was switched on by the airflow meter.  Have you actually wired it to the ECU?

If it is controlled by the ECU the pump should stop as soon as the engine stops - regardless if it is due to a stall, stop switch, or hitting a wall at 100mph...
