Passed the sniffer test with flying colors, however I failed the evap pressure test. Has anyone had any experience with this?
The only components that were disturbed since the last emissions test was the fuel pump and sending unit. New Honda pump in original box (perhaps the last in existence) and a j/y sending unit from a low mile accord. Could it be a seal issue???
Background info...had car parked out in the Arizona heat for the last 6 months. I would occasionally go out and start it. One of the things I would do beforehand is loosen the fuel cap and relieve the pressure from the tank (that swooshing sound) before getting in and cranking it over. The fuel tank has always held pressure just fine (during fill-ups and such).
Recently, including today (emissions test day) that hasn't been the case...no swooshing...no pressure.
I'm pretty sure they kinda disable the charcoal canister by clamping it off and performing the test. They clamped something off, I just couldn't see what from the penalty box they had me sitting in.
The service manual mentions a 2 way valve as part of the evap system, and mentions how to test it with a vac gauge. Same with the canister...I'll test them if it comes to it.
Just hoping that someone has some insight on this before I drop fuel tanks and get knee deep into this thing.
Thanks everyone.
