1999 mercury sable: cranks over great but will not start; happens only when it is cold. Starts fine when outside temp. Is above 40 or so. Shows no codes; have had fuel pump, filter, relay switch and engine temp. Sensor replaced. Still having same problem. I have no idea whats up.

Love this site btw :)

When it doesn't start, check to make sure fuel is getting to the engine even though you replaced everything. Also, check to see if you are getting a good hot blue snapping spark to the plugs.
