2004 Chevrolet Malibu will not turn over

Customer Question

2004 Chevrolet Malibu will not turn over

Hello and welcome!

My name isCustomerand I can assist you with your question.

Customer: replied 10 months ago.
I have Chevrolet Malibu that has a new battery and new ignition starter switch, but still will not turn over.
Customer: replied 10 months ago.
I had been able to jump start the car, but now it will not even jump start. Local mechanic mentioned that the car was not recognizing key and that I need to take to dealer to re-program, but I am not sure that is the issue.
Customer: replied 10 months ago.
I see the car with lock through it on the dashboard when I turn the key. I can make the car turnover by shorting starter or starter relay, but it will not start.

Can I start by getting your VIN?

Thank you!

Thank you for that information.

Are there any codes in the computer?

Are there any anti theft or security lights on or flashing on the cluster when trying to start the engine?

Customer: replied 10 months ago.
No computer codes. The lock thru car light comes on when I turn ignition to start. In the past then anti theft light used to flash, but after putting car in shop 3 times for not starting that light no longer is flashing.
Expert:  AMEDEE replied 10 months ago.

How did you check for codes in the computer?

Customer: replied 10 months ago.
Tester showed 0 codes.
Expert:  AMEDEE replied 10 months ago.

Did the shop disable the theft light?

Customer: replied 10 months ago.
No.
Expert:  AMEDEE replied 10 months ago.

Ok, you will need to check the starting circuit to see where the circuit is losing power. I would go right to the relay and check for two powers and one ground with the key in the CRANK position. This is on the female pins (where you plug the relay in) with the relay removed.

Customer: replied 10 months ago.
I did that and I am getting power to the relay. I can short the relay and make the motor turn over, but when you turn the key the motor will not turn over.
Expert:  AMEDEE replied 10 months ago.

So is the relay getting grounded to activate?

Expert:  AMEDEE replied 10 months ago.

I would be willing to bet not..

Customer: replied 10 months ago.
I replaced ignition starter switch but I did not replace switch cylinder. Local mechanic says car not recognizing switch, so dealer need to re-program.
Expert:  AMEDEE replied 10 months ago.

So what needs to be programmed?

Customer: replied 10 months ago.
Switch to recognize key.
Expert:  AMEDEE replied 10 months ago.

Ok, so did they do that?

Customer: replied 10 months ago.
No, I have not taken to shop because that switch does not have passlock sensor on it, so it seems to be all mechanical.
Expert:  AMEDEE replied 10 months ago.

So if it is mechanical, why does it need to be programmed?

Customer: replied 10 months ago.
That is what I am trying to understand?????
Expert:  AMEDEE replied 10 months ago.

Would you be willing to speak on the phone?
