I recently bought a 99 civic gx on ebay and when I tried to fill it, it would not take any cng. I thought it might be because it had difficulty going into park, I had the cable repaired at s.f. honda but they said it would need a new regulator for over $700 installed and they are not even sure if this would fix the problem, they said it may need a new tank for several thousand $$$$. Has anyone experienced a problem where no gas would go in at a fast fill station. Also, the repair guys seemed clueless even though it was the dealership, is there any place in nor cal that works on these issues with mechanics that are experienced?
