Put a code reader on it should tell you a code for powertrain

Most modern cars have a security code enable for the installed radio/cd players. This is an anti-theft device.

The initial documents given to the owner when the vehicle was purchased lists this code and how to reset it.

If you are second owner/original owner who has lost this information, then, you can approach gmc canyon dealer and they will have this code on their server. Normally a free service (I believe).

The security code is lost from the radio whenever keep alive voltage is removed from the radio. i.e. You disconnected or replace the battery.

I hope this helps.

The cam solenoid may be bad/worn out or the screen is blocked causing this code . States vary on emissions.

That's a misfire code, does the vehicle feel like its running rough? If not it may just be a bad batch of fuel or even time for a tune up depending on mileage.

look at the gas cap seal

The simplest method is to spray the components with something like carburetor cleaner that would cause the engine to lug down when the carb cleaner hits the cylinder.

it means that your fuel is running too rich,and needs more oxygen for a cleaner burn. i think that your oxygen sesor may be faulty,but have autozone run the trouble codes for you,and see what exact part is bad.

You can to the Salvage Yard for a new computer, but your going to have to get it reprogram to your ignition keys, so the Passlock will start the engine. Before you go through all of that. recheck every thing, it could be your crank sensor or your ICM faulty causing your engine to shut down. Keep me posted and let me know what DTC codes you have. Note: a faulty fuel pump or dirty fuel filter will not set a DTC code. You may have a dirty fuel filter or faulty fuel pump or faulty fuel pump wire harness or fuel pump relay.
