Question about 2000 GMC New Sierra 1500
I had an issue with the passlock system in my 2000 GMC1500. The vehicle would start for 1 or 2 seconds and turn off. I put a new key and tumbler in and now it starts and stays running but the message center keeps showing the Battery and Security light. Now it says I have no gas and wont show what gear its in. I know there is gas in it, I just put 15 gallons in and it didn't move the gauge. Is this a Passlock ssue or is it everything happening at once?

Tips for a great answer:
Ignition is in the RUN, START, or ACC position and security system diagnostics have all PASSED
SECURITY TELLTALE will be on if:
The BCM is performing a bulb check at vehicle start
Security system diagnostics have not yet completed at vehicle start
A security system diagnostic trouble code (DTC) is set in the BCM or PCM
SECURITY TELLTALE will be flashing if:
The tamper hall effect sensor has been triggered
Incorrect passlock sensor data to BCM for more than 5 seconds during vehicle start
No passlock sensor data to the BCM for more than 5 seconds during vehicle start
Incorrect password from the BCM to the PCM after 5 seconds during vehicle start
