P1626 won't run
DTC P1626 Theft Deterrent Fuel Enable Signal Not Received
The control module communicates with other modules using the Class 2 Serial Data circuit. The vehicle theft deterrent (VTD) (Passlock) module sends a vehicle security password to the control module, via the Class 2 Serial Data circuit, after the system has sensed the proper operation of the ignition switch and lock, and determined that the switch and lock have not been tampered with. If this password matches the password stored in the control module, fuel will be enabled. If the VTD (Passlock) module does not send a password, or if the control module does not receive it, the vehicle will not start, or it may start and stall. This will set a DTC P1626 in the control module memory. If communication is lost after receiving the password, the VTD (Passlock) system will go into Fail Enable, set a U1192 in the control module, and the engine will continue to run. This will allow the engine to restart on future ignition cycles but may set a DTC P1626 as the engine is started. If the battery is disconnected or the codes are cleared, the vehicle will lose its Fail Enable status and will not start until communication is re-established
Go on YouTube an search passlock by pass , or you can take it to the dealer .

That was a good suggestion by Molson. Also, if you have been doing a lot of heavy hauling, have them check the strainer, which could be a problem as well.

There are special tools and know how requried. If you are asking this question I suggest that you take your truck to a front end shop for this job. It is easy to get seriously hurt.
