Hello, my name is Bobby. Can you tell me what it is doing when you try starting it?
Customer: replied 2 years ago.
Lights come on but it does not turn over.
Expert:  FIXITMAN replied 2 years ago.
Thank you. Is the security light on when you try cranking the engine?
Customer: replied 2 years ago.
Do you think everything has to synchronize and it takes a while to do?
Expert:  FIXITMAN replied 2 years ago.
Yes, all of the computer need to communicate and if it has not been turned on in a while this can happen. I would also try resetting the security system. Turn the key on to the run position and leave it there for 10 minutes. Then turn the key off and back to run for 10 more. Then do this a third time. After the third time see if it will start. Also make sure that the vehicle is fully in park.
