Got my recon turbo back this morning and spent this afternoon fitting it. Come to start the car, and it wont start. Turn the key. ignitions on but it wont start. I have checked all the wiring and its wired as it was before i removed the turbo.

Currently the black blue wire is on to the starter with the battery cable and the blue wire is on the solenoid. On ignition theres 9.2v on the blue but it doesnt change when you go to crank. Should this top up to 12v on cranking. If so where does the wiring run to or does anyone have any other ideas please why it wont go.
