1999 buick regal gsx no crank.
I was 90 miles away from home. I shut the car off for one minute and no crank. New battery good starter. I can jump starter at starter solenoid and relay. Cranks fine but no start. Key reads same resistance on wires as key so cylinder is good. I did order a new if switch and installed it. Have power to switch and thru switch. Vats maybe ? I'm looking for a wiring diagram. I tried the relearn on the ignition. I have no power at neutral safety switch on yellow or purple wire. The security light is solid on no flash. No crank help please. Ty
