Car Won't Start When Left Outside

Hello,

I have a '98 Honda Civic that is regularly maintained and seems fine with the exception of a starting problem when left outside. I have it in a garage normally and have never had a problem starting it. But when left outside, it usually takes a couple of hours for the car to warm to the outside temperture as it rises. The battery is new and the spark plugs seem fine so I am at a loss.

Thanks!

The problem might be with the main fuel pump relay being effected by the temperature. These relays have a history where the solder joints crack inside them and the fuel pump doesn’t operate. This can happen when the interior gets cold or hot.

The relay is located behind the dash, above the drivers left knee.
