I drive a 94 Nissan 4x4 Pick Up. Recently the temps in Colorado have fallen into single digits and the truck doesnt want to start in the morning or in the afternoon. It turns and turns and turns then eventually it will kick over. This only happens after its been sitting in the cold for a few hours. I've tried numerous amounts of dry-gas, carburator cleaner, the fuel filter is about a year old, new battery and alternator. Any ideas?
