Turning my ignition on and wont turn off because it is faulty.
On some Grand Ams if the batteries dead you can't turn the ignition off completely. Try taking the shift lever from reversed to park. Then try to turn it off.
The ignition swithch has failed and is making a continued contact

Defective ignition switch.
May have to be turned off manually Auto sensor bad
With the cylinder removed there is no easy way to turn the switch it would normally operate to the "off" position.
check your relay for the cooling fan and fuelpump
Your battery is dead. Turn your lights off next time.
Run the RED wire to a circuit controlled by the ignition switch. Only the yellow wire should run off the battery, or an "always hot" circuit.
suspect bad fuel filter first, then fuel pump, alternator or battery, ignition module...
