Can a bad coolant temperature sensor keep the car running?
Your symptoms are a dead ringer for a bad engine coolant temperature sensor (ECT). The computer is calculating an air/fuel mixture that is too lean. That’s why pumping the gas pedal keeps your engine running. You can have a bad sensor even without a “check engine” light or trouble code.
Why does my car not start in the morning?
Bitter cold weather can make starting your car in the morning a real pain. There are two fundamental reasons why freezing temperatures make starting a car difficult.

Is a car starter affected by cold weather?
In some cases, especially in very cold weather, starters motor amperage demands can be even higher than normal , which can compound the problem. The issue is that motor oil gets thicker when the weather is cold, especially if you’re dealing with a single weight oil that doesn’t have different viscosity ratings for cold and hot weather.
In cold weather, engine oil becomes thicker and doesn’t flow as well, so moving the engine parts through it is harder. That means that your battery, which has been weakened by the cold, actually has to do more to get the engine moving so it can start. Reason 3: Cold weather can cause fuel problems
Why does my Nissan Frontier not start in cold weather?
“If the engine is very hard to start in extremely cold weather or when restarting, depress the accelerator pedal a little (approximately 1/3 to the floor) and hold it and then crank the engine.

How to troubleshoot hard power steering when a vehicle is cold?
If the techniques you try at home don’t work, take the vehicle to a professional mechanic to ensure that the vehicle will not seize up on the road. Let the car warm up for a couple of minutes before you drive. Power steering fluid becomes more viscous in very cold temperatures, and doesn’t flow as well as it normally would.
It’s a common occurrence as low temperatures can cause your car battery to produce less current, making it that much harder for your engine to turn over in the morning. The cold can also stop your engine oil from flowing as well as it should, which puts even more strain on the battery.
What happens when you start a car in cold weather?
When you start the car, you will notice that it idles high for a period of time until the engine warms up. This is the enrichment cold start process. This is done with what is called a cold start injector which injects more fuel into the motor until the engine reaches a specific operating temperature.
