So my girlfriends 04 Mach1 won't start. Thought it was the battery so I warmed it up, re installed it and it just cranks. It sits outside all the time so I figured it might be a frozen fuel line or something. Jeff told me to take the cap off the fuel rail and push the pin. Some fuel comes out put not a lot. Apparently it refuses to start every winter and it's her only car. Any ideas?
