on my 89 project car i bought one of the previous owners mounted a push button switch in the ash tray with two wires running out to the solenoid and that is the only way it will start. I am trying to figure out how to get it back to stock with key start i disconnected the wires and tried the key and i got nothing i did replace the lock cylinder because the second day i had the car it locked up in the off position and i had to drill the tumblers out to replace it. Thanks for the help guys.
