I am very sorry you are having this issue with your vehicle.

I will try my best to answer all of your questions.

However, before we get started, please let me mention a few things.

1. If at any point you would like to speak on the phone, please feel free to request a phone call on your end and I can call you right away.

2. If you don't understand any technical terms or anything that I mention (component tests or theory or operation), please let me know and I will provide you with a more in debt explanation or answer.

3. Please understand that I am here to help.

Does the check engine light come on at all?

Have you checked for codes in the computer?

Does the engine crank over and not start or does it not crank over when this happens?

DOES NOT CRANK OVER
Cadillac Mechanic: Amedee, Cadillac Technician replied 10 months ago
Thank you for that information. Have you checked the inputs to the starter relay?
Ask Your Own Cadillac Question
Customer reply replied 10 months ago
no
Cadillac Mechanic: Amedee, Cadillac Technician replied 10 months ago
I would recommend to do that next. The relay needs to powers and one ground to operate. This of course is with the key in the crank position, so you will need an assistant to help with this. Let me know!
