I am helping a friend with a 1987 GN. He rebuilt the engine and cannot get it started. We have no spark and no injector pulse. We've gone thru the no spark/injector trouble shooting procedure from Vortex Buick and it points to the crank sensor, but he has already replaced it with an Advance Auto model and still no start.
Is there a way to test the sensor with it off and attached to the cars wiring? Thanks guys and gals!!!
