I bought a 2000 Ford Contour in December for fairly cheap. Getting it to run on CNG is pretty tough. So I decided to probe into this thing they call a Compuvalve. I went to Pick-N-Pull in West Valley City and grabbed a Compuvalve off a 98 Contour with 115000 miles. I didn't expect the unit to work, I just wanted to rip it apart and study it. 20 dollars and it was mine.
I brought it home and disassembled it. Less complicated than I thought. I decided to clean it throughly with alcohol and put it back together. It was fairly clean inside. The dirtiest part was where the injectors spray, it looked like ear wax. I then decided to swap it with the unit in my car.
When I got to mine, I was discouraged to find that it had 4 solenoids, and the junk yard unit had 5. They also had different model numbers. I decided to proceed with the swap, as I figured there was nothing to lose. So with the junkyard unit installed, I reconnected the battery, and hit the ignition key. Just then, the strangest thing happened. The little green light on my fuel switch stayed green! It was not blinking!!!
I thought to myself, no {non-expletive deleted by moderator} way this is going to work. I turned the key and that {non-expletive deleted by moderator} Contour started right up on CNG!!! I couldn't believe it. I haven't been able to use CNG for months! A 20 dollar junkyard part and my car works again. I just hope it lasts until I can buy a different CNG powered car and ditch this beater.
