I have tried three times to get my 2002 Chevy Cavalier to pass emissions test at the Davis County Safety and Emissions testing station in Kaysville, Ut - it's failed all three times because the technicians say they can smell fuel. The CNG shop says the car has a fogging system and that a small smell of fuel is common. Is this true? Does anyone have any documentation that I can show the technicians on try number 4?
The first time it failed because the technician said we needed the tank certified and they smelled the fuel.... we've always smelled a little fuel in cold whether... sometimes more than others, no smell in the summer.
We took it to the Bountiful CNG shop and they certified the tank and went through the entire CNG system. $300 later they certified the tank and said there was no fuel leak - the system was a 'fogger' system and the smell was common with that type of system. We were back at Davis County Emissions for try number 2.
The second time the technician refused to even test the car/look at the tank certification because he said he smelled fuel.
We determined that we would just run the car out of CNG and take it in runing on gasoline... once the car ran out of CNG, the gasoline fuel pump didn't work - coincidentally????? it worked fine before the CNG tank certification process. A new gasoline fuel pump, another inspection of the CNG system and a replacement of one of the CNG gaskets (they now said they did find a small pinhole in it) - $900 later and we were up for try number three.
The third time I took the car in right after picking it up from the CNG repair shop. I had it running on gasoline - the technician again said he would not even inspect it because he could smell CNG. I lifted the hood and couldn't smell a thing, opened the trunk and couldn't smell a thing. No smell in the car.
How can I get my car passed if the technicians are saying that they can smell fuel? I can't afford any more trips to the CNG repair shop and I need to get my car passed. This has been going on for 3 weeks... only 6 days left in the month before the license plates expire.
Any suggestions? I don't want to have this kind of problem/expense every year. Does anyone have the tech notes for this 'fogging' system on the cavaliers that identifies that there can be a fuel smell?
Has anyone else had issues with the Davis Emissions on their CNG vehicle?
