Hello, my name is \*\*\*\*\* \*\*\*\*\* to Just Answer! I will be assisting you with your questions today. Give me one moment while I review this.
Automotive Expert
The most common cause is a bad or plugged VENT valve in the EVAP system. This is located on or near the charcoal canister near the fuel tank. You can test the valve with a scan tool too. Hi, I’m Ron and I’m here to help you with your problem. I’m very sorry that your having this issue and together, we will get this figured out. I will need your help too because I can’t see, touch, hear or smell anything that’s going on with your vehicle. We may also require some testing tools in order to assist us in diagnosing the problems due to the complexity of today’s vehicles. Most parts stores will read codes for you for free with only a code reader, and sometimes that’s all we need, but not always. Please let me know when you are satisfied my answers too so we can close out your question. Thanks a lot for using JA, Ron

Alright, should I get to an Auto Zone or what have you? I am in the process of moving and in a different state from my home so my tools are slim
Automotive Expert
They may have that part, yes. Thanks again, Ron

Alright, I will get to an Auto zone. Then what would I ask for? A code reading? My check engine light isn't on
Automotive Expert
It may not set a code for a VENT valve, especially if the computer thinks it's working. Hence the reason for the scan tests in bidirectional mode. Thanks again, Ron

Will they be able to test it or do I purchase the tool to test it?
Automotive Expert
They can with a scan tool, NOT a code reader. Thanks again, Ron

ask if they have a scan tool not a code reader
Automotive Expert
You're welcome. YES. Thanks again, Ron

They only have pressure testersSaid since fuel gauge isn't reading correctly said to use multi meter
Automotive Expert
Wrong tests and answers. You have 2 choices, just replace the valve or have a shop diagnose it. Thanks again, Ron

There is no power going to fuel pump. Check relay it's good.
