What can I do the passlock keeps coming on and interrupts the caes running. I have tried to remove it but it keeps coming.

There is NO way to disable PassLock. It's an anti-theft device. Disabling it would defeat the purpose of anti-theft---Unless you know how to dig into the software and rewrite it. Fix it.

I installed a new steering column in my 2004 Pontiac sunfire and now it will not start. It tries then I beta back fire.

Anti-theft system isn't allowing it too .
The Passlock™ System is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. If starting is attempted without authorization from the Passlock™ System, the powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
The components of the Passlock™ System are as follows:
• The ignition lock cylinder and key
• The ignition lock cylinder case, including the Passlock™ sensor
• The ignition switch
• The body control module (BCM)
• The security indicator on the instrument cluster
• The powertrain control module (PCM)

2002 suburban start and dies, its not the fuel pump. what is it

Is there a security lamp on the dash that is on or flashing? Any applicable trouble codes? My info shows you have passlock, usually a fuel injector disable, only, may start and stall. If vehicle starts and stalls, leave key in the on position, If security lamp does not flash, the passlock system should not be at fault.

Security light is on my 1999 Chevrolet suburban how to reset it

Passlock on this vehicle shows the key does not have a pellet and no transponder. It's just a mechanical key. It is the tumbler that communicates with passlock sensor. The passlock sensor wiring is noted for problems. Can you check applicable trouble codes?

I have a 1999 GMC Suburban. It isn't starting, not even turning over but the lights and radio go on. Could it be the starter?

It could be the antitheft security system failing. Its called passlock. These are known for disabling starters, and GM's are known for this problem.

Instrument panel warning has an image of car with a lock?? I drove it for a while then it disappeared?

Passlock system indicates an error. Your BCM doesn't see the correct password. This could be the passlock sensor (most common on these vehicles).
