Fuel pump will not energise. With plug CO1-2 removed from ECU shorting pin 4 to chassis energises ECU relay which energises the fuel pump. ECU repaired.

Attached are the schematics for the fuel pump.

Do you have ignition sparks? The fuel pump relay requires ignition sparks (cam sensing) to energise it.
