I HAVE HAD PROBLEMS PUMPING GAS INTO MY TRUCK, THE HOSE

Customer Question
I HAVE HAD PROBLEMS...

I HAVE HAD PROBLEMS PUMPING GAS INTO MY TRUCK, THE HOSE NOZZLE SHUTS OFF LIKE IT WOULD IF THE TANK IS FULL. I HAVE A 2012 CHEVY 1500, 5.3 L. ENGINE. I ALSO HAVE HAD A CHECK ENGINE LIGHT ON, CAN YOU HELP?

Mechanic's Assistant: Does the light stay on, or does it blink?

STAYS ON.

Mechanic's Assistant: What is the model of your '12 Chevy?

C 1500 SILVERADO EXT CAB

Mechanic's Assistant: Are you fixing your Silverado yourself? What have you tried so far?

I FOLLOWED THE DIRECTIONS IN THE MANUEL, USING A HIGHER OCTANE GAS. I ALSO CHANGED THE GAS CAP, THE COMPUTER WAS GIVING A MESSAGE THAT THE GAS CAP WAS NOT CLOSED.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

THE HIGHER OCTANE GAS DID WORK FOR A TIME, BUT THE CHECK ENGINE LIGHT WOULD COME BACK ON.

Hello, my name is***** will be helping you out! I have over thirteen year of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

Do you happen to have the check engine light code available?

It appears to be a fuel evaporation issue

Where do I find this code?
Chevy Mechanic: Mike, Auto Mechanic replied 10 months ago

By going to your local auto parts store and let them put it on the scanner, more likely will have an evap fault

Were you able to retrieve the codes? If not, would you like for me to tell you what sensor could be the problem and all other possibilities?

Code P70455
Chevy Mechanic: Mike, Auto Mechanic replied 10 months ago
Ok I'll look up all the details and get back to you shortly

Chevy Mechanic: Mike, Auto Mechanic replied 10 months ago

ok here are your three possibilities for the p0455 code, Evap purge valve, Evap vent valve, or the inlet check evap valves.

I will enclose all information relating to evap system operation and including procedure to remove the purge valve and the vent valve.

On the evap document it will say on top chevy express, dis regard that because your system is identical. In the evap document you will see standard location of the check valves.

To find out which of the three you need to replace, it will need to be diagnosed properly. If you just want to "try" a part and see if it fixes it without spending too much money & without hard labor, it would be the evap purge valve. It is pretty accessible under the engine cover. Maybe ten minutes to change it. If you need anymore help or infor let me know, Thank you. Sincerely, Michael.
