hi called out to look at friends car, car wouldn't start 2009 insignia 2.0 cdti,delphi diagnostics came up with clutch pedal switch low voltage p0807,replaced the switch with genuine gm no change and it has 5v going to the switch,tried re learn on clutch pedal with Delphi and just fails after prompting to depress clutch pedal,does the switch need recalibrating when replaced?will op com calibrate/re learn the switch or would have to be tech 2? I can start the car by bridgeing terminals on starter,anyone got a link to wiring diagrams for the starting system,related fuses relays,any help or info would be much appreciated thanks dennis
