Trouble Starting Car After Sitting Overnight

Make sure that you’re not trying to start the car in gear. This is a common mistake when people first learn how to drive a stick shift, but it can also happen if you’re used to driving an automatic and are suddenly driving a manual.

Make sure that all of the interior lights are turned off. This includes dome lights and headlights as well as any other lights that may be on inside of your car.

If your vehicle has been sitting for several hours with these lights on, they could drain enough power from your battery to prevent it from starting when you try to start it again even if the ignition is off.

Causes of Trouble Starting After Sitting Overnight

The first thing to check is your fuel. The fuel may have gone bad, or it may need to be changed. You can use a fuel stabilizer to keep it fresh for longer periods of time.

If you’ve been storing your car for more than six months, consider changing the fuel if you can’t remember the last time you used it. Another possible cause of trouble starting after sitting overnight is dirty spark plugs or wires.

A simple tune-up will fix this problem quickly and easily. You may also need new air filters or filters for your fuel system if they haven’t been replaced recently.

If these aren’t the problem, then look at how much oil is in your engine and whether there’s a leak in any of the hoses or other parts that could be causing problems with starting up again after sitting overnight.

Check the fuel tank

If there’s no gas in it, then take a look at the gas gauge. If it shows that there’s gas in the tank but still no start, then your problem is probably not with the fuel system at all it could be something else.

Check the battery

Maybe it’s time to check the battery. If a car sits for long periods of time—more than a day, usually the battery can lose its charge, which may lead to problems with starting and charging.

Check the starter

The starter may need to be replaced if it’s not working at all, or if it’s only working intermittently. A lot of times, this means that the starter has worn out and needs to be replaced.

If you have a mechanic check the starter for you, they’ll be able to tell you whether it needs replacing or not.

How to start your car if you have trouble on a cold day?

The first thing to consider is whether or not you have enough gas in the tank. Most cars will require at least 5 gallons of fuel before they’ll start up again. If you don’t have enough gas, what’s known as stale fuel can clog up your engine and make it hard to start.

Another thing to check is the temperature of the engine itself. If it’s been sitting outside overnight and is still very cold, let it sit for another 15 minutes before trying again. The engine needs time to warm up before it will turn over again.


It’s clear that the key to a trouble-free start is to make sure your battery is in good health. If you follow these steps and check in with your battery every once in a while, you should be able to avoid any issues.
