What they mean is the EVAP system. You probably have a bad solenoid in the EVAP behind the gas tank. It's not opening to let pressure escape. The negative pressure will build up and cause a vacuum, not letting the fuel properly flow. Here is a video: https://www.youtube.com/watch?v=-WY5EVU8sj0 You will probably want to let the shop handle this. Very hard to get to unless you have a lift.
Thank you ya I meant evap system. Is it expensive to fix?
Yes. If you buy an after market vapor canister it will run you from $205- $380. Not including labor to install. You can try your luck at a salvage yard. No idea what they will charge. Just bring a 9 volt battery with you with two wires. You will need to hook it to the canister and check to make sure the solenoid is working. Just like they did in the video.
