Trouble Starting After Getting Gas

[hottbodyz]

After getting gas the last few times my 2019 Sierra has a hard time starting and runs rough for a few minutes when it finally does start.
So far I have changed the vapor canister vent valve on the motor and the vapor canister solenoid underneath the truck with GM parts.
Neither has worked to fix the problem. Any ideas?

Have you checked the fuel pump and pressure?  How low do you let the fuel tank get before you refuel?

 

What is the engine temp?

Still having the same issues with the truck.  Now this is odd. When I stepped up into the bed of the truck yesterday this noise came from underneath the bed. What is this ? and maybe its the cause of my issues? Very strange

Do you stop filling the first time the fuel nozzle clicks or re-activiating it multiple times to squeeze in as much fuel as possible?

I always stop after the pump clicks off. I know it would cause problems otherwise.

Sounds like the parking brake engaging.
