Default Problem with starter/immobilizer

Hello guys, I need a help, please.
Ignition goes on, brake light was broken, so we bridged it. Lights on dashboard go in but the starter does nothing, not even a click. Immobilizer light on Dashboard is sometimes on and after starting attempts it goes off. Battery power is available enough

Welcome. What is the voltage of your Battery at rest?

If your brakes had a short, as in the common wiring rubbing the chases above the license plate which you can see between the bumper with the back swing gate open, then your battery may be too week and still shorting.

Year and Miles is always important.

Otherwise look up GM PassLock.

Let's start at the beginning.
Have you recently done any work or add ons?

1. Battery Internal damage
2. Ground strap too block/frame
3. Power wire to starter
4. Fuses
5. Fuse box failure
6. Starter shorted
7. Passlock failure
