HI,

I am sorry that you have not been helped. I just came online and saw your question

This may be an immobilizer issue, or even a low voltage condition if the battery is not holding the charge you put on it.

Check the voltage at the battery and let me know what it is at this point

Also, is the anti-theft/security light blinking on or staying on steadily

The voltage at the battery is 12V it is now charged and working fine in a sense that the starter does turn... just the engine electronics are not working including the dash board. The key locks work fine.... How do I resolve an immobilizer issue?

HI,

Is the anti-theft/security light blinking on and off or staying lit as long as the key is in the ignition?

If either case is happening, then it is an immobilizer issue and will require a high end scan tool to diagnose it. If neither is happening, then it is not an immobilizer issue and will need to get into the electrical system at this point
