  post locked   99 ford contour bifuel  

I have a 99 ford contour bifuel it runs on both gasoline and cng. I'm looking for a ford mechanic whos worked on these before. I threw a p 460 code which has to do with the fuel gage. It got stuck on full and would only run on gasoline not cng. I've had it to an electric guru who colud not find the problem I need a mechanic whos dealt with this problem before. I can fix everything but i'm lost with electrical problems. A few years ago i bought a complete wiring diagram on line it laid everything out in 1 diagram can anyone help me.

I have a cng contour acting up. Mine only runs on cng. I had a local mechanic look at it and there is a bifuel module that controls the conversion when you switch from one fuel to the other. It switches the fuel gages and the gas fuel pump on and off, and some how turns the cng on and off. Does your wire diagram show that device? He can not find information on how to test the device. The info I downloaded from ford indicates that if yours runs only on one fuel or the other the bifuel moduel could be the problem.
