Do you have a check engine light on? If so get a auto parts store to scan this and tell us which code or codes are present and get all the information from the employees doing the scanning too, Unless you know for sure the sensor it says to fix is cheap or has a problem for sure do not spend the money for it just now as the can be many reason a code can set that just affects that sensor while the sensor is good so those reason need investigated first, just let us know we will try to help.

This may be related to the antitheft system. The system is known for turning off the starter and/or injectors when it fails. Normally when the injectors are turned off, the car will run for a second or two, and then stall. When it's the security locked out starter, you won't even hear a click when you turn the key. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. http://www.diy-gm-security.com/ & http://newrockies.com/

I do not have an check engine light. About a year ago I replaced BCM and had the dealer program it, and everything has been good until about a month ago. Started having problems with the AC and information center not coming on then no power to the fuel pump. I was told it was the ignition switch, replaced that and it worked for a couple of days and now sometimes the fuel pump doesn't get power so it won't start just cranks.
