I finnaly got the car started and hear the fuel pump making noise that seems to loud!! The car starts and can take key out and disconnect battery and still runs. The only way to turn off is brake pedal shuts car down. Can a bad alternator or some other part make this happen. Even with the key not in I wiggle the + battery wire and the cars dash lights up. Can this be a voltage regulator problem. Need advice on where to start thanks.
