What Do You Do if Your Engine Floods?

We have all heard the horror stories that friends have told about flooded engines, flat tires, smoking engines and everything else under the sun.

In the event that they do, it is important to know how to react and what the proper course of action may be, whether that is calling the Downeast Toyota Service Department or taking care of it yourself. A common question our service technicians get asked is — what do you do if your engine floods? Take a closer look at why this happens and how to best address the situation.

How Does Your Engine Get Flooded?

A more common mechanical ailment for cars that employ a carburetor rather than fuel injection, a flooded engine occurs when your engine is overcome with too much fuel. This happens when there is a disproportionate mixture of fuel and air and will typically occur when you hit the gas too hard or pump the accelerator too much when starting your car. Vehicles that employ fuel injection like the 2016 Toyota Camry will see this happen most often when in extreme cold.

How to Start an Engine After it is Flooded?

Perhaps the best remedy for a flooded engine is time. Simply open the hood of your car and let excessive fuel evaporate for as long as you can. After about 20 minutes try starting your car again without hitting the gas pedal. If this still does not work, you may have to check your spark plugs. When excess fuel floods the engine, it can soak spark plugs, making them incapable of creating enough of a spark to start the engine. If you find that your engine floods frequently, you may want to check your fuel injectors and run some fuel injector cleaner.
When you are troubleshooting a flooded engine, the end goal is to establish the correct fuel to air ratio. Another thing you can try to make this happen, is to hold the gas pedal to the floor and repeatedly attempt to restart the engine. Do not pump the gas pedal. This method will hold the throttle open, introducing more air into the engine to balance out the excess fuel. When the engine starts, release the gas pedal and let it run for a few minutes. Should this method fail, it may be time to schedule a service appointment with our expert service technicians at Downeast Toyota.
