G40 Crank Position sensor wiring

[Demo8Dan]

Hi all does anyone know where the wiring goes to for the crank sensor so I can test them out. I'm only getting voltage on 1 of the 3 wires and car is poor on starting. We have replaced the g40 already with new and stripped timing down and re done it which is spot on now but still poor on start. Fuel pump has also been charged.
Any ideas or tips would be greatly appreciated [emoji846]
