Your GMC Acadia, like any other vehicle, can develop mechanical issues and fail to start. What should you do in such a situation? We received the following responses from car experts after consulting with them.
These are the most common causes of your GMC Acadia not starting:
Continue reading to learn about the causes of your GMC Acadia not starting and how to restart it. Additionally, learn how to maintain your car so that it lasts longer.
Your car not starting is an issue that can occur at any time. But did you know there are ways to figure out what’s wrong and how to fix it? Let’s take a look:
If the battery is dead or weak, the car engine will not start. To check the battery voltage, use a multimeter.
Unlike most cars, the battery in a GMC Acadia is located beneath the floorboard between the front and rear passenger seats.
To get to it, flip the mat over and unscrew the single screw that holds the battery in place.
Connect the multimeter’s black end to the battery’s negative terminal. Similarly, connect the red end of the cable to the battery’s positive terminal.
If the reading is negative, you’ve connected it incorrectly. Instead, connect it in reverse to get the correct reading from the device.
When the car engine is turned off, the ideal car battery voltage is 12.6V. If it reads less than 11.9V or more than 13V, a car expert will be required to inspect it to determine the cause of the problem. It could be damaged and needs to be replaced.
If your key fob battery is low, your car may not start. To resolve this, position it as close to the start/stop button as possible and start the vehicle. But don’t forget to replace the battery.
Corrosion on your car battery can cause it to fail to start. If this is the case, you will notice a greenish, blueish, or occasionally white substance that has formed on the battery terminals, cables, or posts, obstructing the flow of electrical current.
But don’t worry; cleaning the corrosion from the battery is simple. To avoid electric shock, turn off your vehicle and disconnect the negative battery cable first, then the positive battery cable. Keep this order in mind at all times.
Your Gmc Acadia typically won’t start due to a broken alternator. Your alternator likely needs to be replaced if the battery charges but drains quickly. It’s possible that the alternator has stopped working or that it’s providing the wrong voltage.
If you’ve tried all of the simple fixes and nothing works, it’s likely that your Gmc Acadia won’t start due to a faulty fuel pump. When you try to start it, a bad fuel pump may make a whining noise.
If you’ve tried everything else on this list and your Gmc Acadia still won’t start, worn spark plugs could be the problem. If your spark plugs are worn, it can result in poor gas mileage and a loss of power. As a result, you must replace them as soon as possible.
A blown fuse can be at blame if the battery’s cables and terminals are clean but the issue still exists. To check, see the list of inside fuses in your owner’s manual. To inspect it, locate the one that belongs to the electrical system and take it out of its socket.
A bad starter could prevent your Gmc Acadia from starting. Possibly, if it rolls over but doesn’t catch, this is the problem. A damaged starter could produce noise but fail to engage.
If your Gmc Acadia runs out of gas, it will not start. So, before you do anything else, fill up the gas tank. If you’ve already filled the tank and it still won’t start, you should check the fuel filter. Over time, the filter can become clogged with dirt, preventing the car from running properly.
When rodents get into your car and bite the wiring, a lot of things can go wrong, affecting many vehicle systems, including the one responsible for starting your car.
Nothing will work because your engine has failed. Overheating, oil leaks, and using the incorrect fuel are all possible causes.
Aside from resolving the issues that are causing your car to not start, you would like it to last as long as possible. Tips for extending the life of your GMC Acadia are provided below:
Change the oil in your car on a regular basis to keep the moving parts lubricated. Check that the oil filter is in good working order as well.
As previously stated, one of the causes of engine failure is an oil leak, which can prevent your vehicle from starting. Always keep an eye out for oil leaks and have the vehicle checked as soon as you notice one.
Avoid driving on reserve fuel to extend the life of the fuel pump. Because sediments from gasoline settle at the bottom of the tank, driving your car with the tank nearly empty will cause the fuel pump to wear out.
Sometimes all that is required is to clean the spark plugs so that you can continue driving your car normally.
When your GMC Acadia won’t start, it can be very concerning. This issue is caused by a variety of factors. Some are simple to fix, while others require you to take your car in for service.
