Hi there,

This usually means the starter is bad and shorting out the cables, or that you have corrosion either at the battery or on the ends that connect to the engine or starter. Look for green corrosion or swelling inside the cable insulation.

If the engine is cranking and not starting then it is likely the latter.

Please let me know if there is any more I can do to help you from here.

One month old battery, cables are new looking. The negative side post was loose, tightened it up, nothing happens, took the battery out to be checked on load all checked out fine. Two lights are on, the check engine (yellow) and the red check Gages light I think it's a security key issue. How can I check that I only got one key when I bought it last week, they are sending me another key fob and key by mail

Do you get a click or anything when you turn the key?

Customer: replied 2 years ago.
Nothing , no solinoid click
Expert:  Mike V. replied 2 years ago.

The anti theft should not make the battery cables get hot.

Are both cables hot or just one and if one, which one is hot?

Customer: replied 2 years ago.
Nothing has been hot it's been sitting since 8 pm Saturday
Expert:  Mike V. replied 2 years ago.

Sorry, I missread what you wrote, it has a hot battery which I assume means a full charge now.

Ok, give me just a moment.

Do you have a test light or a volt meter?

Customer: replied 2 years ago.
Full charge sorry my test light is in my work truck, not here
Expert:  Mike V. replied 2 years ago.

Ok, is it auto or manual?

Customer: replied 2 years ago.
Auto I've tried neutral and park

Let's try the 30 minute relearn for the security and see if it will crank. Here is the relearn procedure.

30 Minute Learn Procedure

  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON (vehicle will not start).
  3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
  4. Turn OFF the ignition, and wait 5 seconds .
  5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the password ***** the next ignition switch transition from OFF to CRANK).

IMPORTANT: The vehicle learns the password ***** the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

  1. Start the engine (the vehicle has now learned the password).
  2. With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles) .

I'm in the middle of the second 10 min section but I don't see any security light or telltale, what is that I'm timing each step even with no sign of security light
Expert:  Mike V. replied 2 years ago.

Looking for a diagram for you, it should be in the owners manual if you got one with the car. It's suppose to be in the instrument panel but GM isn't providing a diagram or location.

Customer: replied 2 years ago.
No manual, they are mailing that also , but the only lights on are the check engine, the check Gages and the red seat belt The security light comes on briefly when I turn the key to start
Expert:  Mike V. replied 2 years ago.

If it's going out then it's probably not the issue.

I am going to open this back up for the other experts to take a look at. Sorry I don't have any more info for you.

Please don't respond or rate me because the others won't get a chance to look at the question. Sometimes it takes a little time to get the right expert to see the question. Without a test light there isn't much we can do.
