We were going down the road and the car died and would not start. It sat overnight and started the next morning when it was cool out. That night after the outside temp warmed up it would not start. This morning again when it was cool it started. I replaced the fuel filter and coil. Now that it has warmed up outside it will not start. Thanks Roy

It started when it the outside temp was cool first thing in the morning not the car temp. Then it sat all day and when I tried to start it later in the day when the outside temp had warmed up it will not start
