Trouble with frigid weather starting

Hi-I own a 1999 Subaru Forester standard transmission. We live in Minneapolis and this winter has been very cold. This morning, I started the car to warm it up and brush snow off it. I wasn’t ready to drive, so I shut it off. About 1 hour later, I tried to start the car and it would turn over but wouldn’t start. It has a brand new battery and the oil was changed in November. Can anyone help?

When was the last time that the spark plugs were changed? How about the air filter and the fuel filter?

Battery connections tight? Starter ok?

A battery and charging system test isn’t expensive, so start there. Your previous battery failure could have been related to a weak charging system. Or your new battery could be defective.
