The white wire with the red stripe is the control voltage wire (has 12v+ when the key is turned to the start position) - the blue wire is ground, but it is not connected to 12v- until the display senses neutral light, park indicator or the brake light.
If you can measure 12v on the wht/red wire with the key in the start position and you are too cheap to take it to a dealer to run the diagnostics and repair the deficiencies, you can bypass the safety features by splicing a ground connection to the blue wire.
BTW - the 'mechanic' you took it to was a jack ass as the stator has nothing to do with starting - the stator is for ignition and charging the battery. If you still have the ols stator, keep it for a spare or offer it for sale on Ebay or Facebook.
