Ok, so I have been doing a lot of trial and error and I don't know where else to go. My 2003 S10 is having trouble when I go to fuel up. It was for a while not taking fuel with a Service Engine Light on as well then I finally disconnected the line to the charcoal box and that fixed the fill up problem. Is it the box that needs to be replaced or is it the solenoid that is connected to the box that may need to be fixed? I am having a hard time thinking it is the solenoid as i don't see how that is really giving me the issues. Any advice would be greatly appreciated.
Thanks
