Can you change a 2005 gmc canyon fuel filter yourself and where is it located

Park the Canyon on a flat stretch of road or driveway and open the hood.

4 cyl or V6 engine ?
I think the 4 cyl is on the side of the block under the manifold.

In a nutshell... Take the intake manifold off and then you can access the fuel rail for removal.

All fuses and circuit breakers for a 2005 GMC Canyon are located in the engine compartment fuse block.

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.

The P0300 is a misfire and P0506 indicates low RPM at idle.

A misfire can be caused by poor ignition (spark plug, plug wire, coil, ignition module/engine control module).
OR
Poor air/fuel (air filter, fuel injector, fuel pressure, fuel filter, fuel pump, bad gas, or engine control module).

Check your maintenance requirements and see if any of these items are due for replacement first.

The canister is located around the fuel tank. Typically above the rear axel.
Good luck.

If you don't depressurize the system you will get sprayed with fuel.
