Hello. My name is ***** ***** I will be helping you today.

Do you have an evap smoke tester or bidirectional scan tool to test with?

Have you tried a new gas cap?

Customer: replied 8 months ago.
No . only gas cap change
Expert:  Wayne Crawford replied 8 months ago.

OK. If the gas cap didnt do it youre either gonna have to throw parts at it till one sticks or pay to have someone with the proper tools test it. You did clear the codes after replacing the cap right?

Customer: replied 8 months ago.
POO440 is the code that popped up
Expert:  Wayne Crawford replied 8 months ago.

Im not sure how to interpret that answer to my question.

Customer: replied 8 months ago.
did clear the codes . im looking for the problem source any idea on were are the most common places
Expert:  Wayne Crawford replied 8 months ago.

The most common problem on these is the natural vacuum leak detection assembly.

Let me know if you need anything further and please be sure to rate my service so I get credit for helping you today. Thanks

Were is the vacuum located under the truck front back ?I do have questions
Expert:  Wayne Crawford replied 8 months ago.

There is no vacuum.. vacuum is created by the engines combustion.

What questions?

K ill keep u googling there helpful. Its a leak would that be the hoses ?or charcoal canister? Ect ect..?
Expert:  Wayne Crawford replied 8 months ago.

If its a leak (which it is as the code states) the majority of the time it is in the NVLD assembly as I just pointed out. Or are you saying you already did that and want the next part to throw at it. It COULD be a leak in ANY of the EVAP parts but the one I already told you is the most common by far.

U suck dude no help at all I could have u tubed what u gave me to work with ✌
Expert:  Wayne Crawford replied 8 months ago.

Im sorry I cant afford to buy you tools. I gave you the most likely cause of your code. I cant tell you how to test when you dont have any tools to test with. Im sorry you feel I suck for providing you with the best information possible based on YOUR circumstances.
