Hi, glad to be of help. First you will need to check for codes with a Tech2 scanner. There are several reasons that could cause the theft deterent system will cause it not to start. Get the codes so you can narrow it down. Some of the Components that can cause this are ignition switch (passlock sensor), BCM, instrument panel cluster and PCM. There are several electrical TSB's on this truck. I would check these out first before spending money to fix it.
Programming Theft Deterrent System Components
Important: This procedure has to be performed only for vehicles equipped with Passlock System.
If the 10 minute learn procedure is chosen, perform the special function for BCM "Request VTD Info. for SPS" or select Service Programming Systems, and then refer to Programming Theft Deterrent System Components in Theft Deterrent. If the Programming Theft Deterrent System Components in the Theft Deterrent procedure is not performed after a BCM replacement, one of the following conditions will occur:
• The vehicle will not be protected against theft by the Passlock System.
• The engine will not crank or start.
This procedure also needs to be performed when replacing the passlock sensor or when replacing the PCM with one used before in a different vehicle.
Relearn Restraints ID
Perform the special function for BCM "Setup SDM Serial Number in BCM" with the scan tool.
This procedure may also need to be performed when replacing the SDM.
Important: After programming, perform the following to avoid future misdiagnosis:
•Turn the ignition OFF for 10 seconds.
•Connect the scan tool to the data link connector.
•Turn the ignition ON with the engine OFF.
•Use the scan tool in order to retrieve history DTCs from all modules.
•Clear all history DTCs.
-------------------------------------------------------------------------
Programming Theft Deterrent System Components
Important:
• If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn Passlock™ sensor data code immediately. The existing PCM however, must learn the new fuel continue password ***** the BCM is replaced.
• If replacing a PCM with a GM SPO replacement part, after programming, these modules will learn the incoming fuel continue password ***** upon receipt of a password ***** Once a password ***** is received, and a password ***** ***** a learn procedure must be performed to change this password ***** A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password, and will require a learn procedure after programming to learn the current vehicle's password.
Conditions
Use this procedure after replacing:
• Passlock™ Sensor
• BCM
• PCM
Learn Procedures
There are 2 available methods to perform the programming procedure:
• A 10-minute procedure which requires a Tech 2 and a techline terminal.
• A 30-minute procedure which does not require the use of any tools.
10-Minute Learn Procedure
Tools Required
• Tech 2
• CANdi Module
• Techline terminal with current Service Programming System (SPS) software
•Connect the Tech 2 to the vehicle.
•Select "Request Information" under "Service Programming".
•Disconnect the Tech 2 from the vehicle and connect it to a Techline terminal.
•On the techline terminal, select "V.T.D. - Vehicle Theft Deterrent Learn" under Service Programming".
•Disconnect the Tech 2 from the Techline terminal and connect it to the vehicle.
•Turn ON the ignition, with the engine OFF.
•Select "Program ECU" under "Service Programming".
•At this time you will receive a screen on the Tech 2 stating to "PLEASE WAIT-MINUTES REMAINING 10".
•Turn OFF the ignition, and wait 30 seconds.

there is no tsb's relating to the concern, if so please reference them, nothing has been replaced on the truck and copy and paste the program procedure from the chevy manual isn't helping at all
Chevy Mechanic: ASEMaster35yrs, Chevy Technician replied 2 years ago
What engine do you have? What are your codes? Do you have a Tech2 scanner?
recall 08142
TSB Correction
Dealers are to reprogram the ECM with revised software that corrects the programming error.

All Recalls & TSB's
https://www.automd.com/tsb/chevrolet_m/silverado-2500_mm/2007_y/?page=2
Ask dealer about recall 08142
You will need a Tech2 scanner to program. You will need to retrieve the codes. A cheap code reader will not help you since you will need to access and communicate with the modules.
When doing a relearn you must first make sure battery is fully charged and in good condition before beginning. If the light never goes out there is a problem that needs to be addressed first before doing a relearn.
Here is the procedure when you're ready for it.
Passlock III Relearn Procedure
30-Minute Relearn Procedure
Use this procedure after replacing any of the following components:
• The PASS-Key III plus keys
• The theft deterrent module (TDM)
• The powertrain control module (PCM)
This procedure is not available on vehicles equipped with EXPORT configured TDMs.
• When performing the 30-minute relearn procedure, all previously learned keys will be erased from the TDM memory. Additional keys may be learned after performing the relearn procedure.
When replacing a TDM with a GM SPO Replacement Part, ensure the procedure to setup a new TDM is performed prior to the 30-Minute Relearn Procedure.
1. With a master vehicle key, turn ON the ignition, with the engine OFF.
2. Observe the security indicator. After approximately 10 minutes, the telltale will turn OFF.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
5. ignition OFF before attempting to start the vehicle.
6. With a master vehicle key, start the vehicle. The vehicle has now learned the key transponder information and/or the ECM has now learned the fuel continue password.
7. If additional keys are required to be learned, continue to step 7.
8. With a previously learned master key, turn ON the ignition, with the engine OFF.
9. Turn OFF the ignition and remove the key.
10. Within 10 seconds insert the key to be learned. Turn ON the ignition with the engine OFF. The vehicle has now learned the new key.
Passlock III system uses a standard ignition key to rotate a specially coded ignition switch.
GM - three security systems currently in use: Pass-Key III (PK3) (transponder based)
system by Megamos, PASS-KEY II (VATS - key mounted resistor) and Passlock which
uses a standard key.
