Why does my Nissan Patrol have difficulty starting in cold weather?

I live in a cold climate and every time the temperature drops, my Nissan Patrol has trouble starting. I've replaced the battery and it doesn't seem to be the problem. Any advice on what could be causing this?

It's possible that your fuel mixture is too lean for cold weather, causing your engine to struggle to start. You may need to have your fuel system checked and possibly have the mixture adjusted.

Check your spark plugs to make sure they are in good condition and properly gapped. In colder temperatures, worn or dirty spark plugs can make starting the car more difficult.

Have you noticed any unusual noises or smells when starting your car? It could be a sign of a faulty starter motor or ignition switch. It's best to have it checked by a mechanic to prevent any further issues.
