Evap problems 2014 4.0

Hey everyone. I have a 2014 dclb 4.0 and recently got a p0174 code. I replaced the solenoid, the maf sensor and the secondary air pump, oem gas cap. Now I have a p0174, and a p0441, p0455. Hoses seem fine. There is one thing, when I refuel it hesitates the first try. Then it starts on the second one. Could this be the fuel pump leaking air? Or what is your experience with evap. Thanks in advance.

 

Check your purge VSV on the left side of the intake, there should be no vacuum present at the port with the connector unplugged and the engine idling. If there is then the valve is bad.

 

Welcome to TW..

 

Charcoal canister is bad, possibly cracked 455 is gross leak

 

Ok will check those two things thanks!

 

Hey guys I put an oem purge vsv. There was a strong vacuum from the sh*tty auto zone part I put on. After that there was an issue with the o2 sensor. I waited till I had some miles to update I will proudly say no lights or codes 400 miles later. Thanks for the help.
