Mx83 fuel pump

[hosking1991]

Hey guys

I got my map ecu installed but I'm pretty sure the switched output to drive the fuel pump is not working properly,

From my understanding the car turns to fuel pump on once the engine is cranking , and the signal comes from the afm?

Is the anyway I can maybe put the fuel pump on a switch? Where would I find the wires for that ??

Thanks Luke

take any 4pin relay and wire like this:
+12v from batt
+12v ignition wired through a switch
-ve
and the output wire to +ve on the pump, either work out which one it is from ecu pinouts, trace the wire back from the boot, or run a new one straight to the pump in the boot

profit??

or go to any LPG installer and pick up one of these for about $30, eliminates the switch and wont fire the fuel pump til the engine is doing 200rpm or more (runs off ignition coil -ve)
