Do this until the engine starts. As soon as it does, let go of the key. 3. If your engine still won't start (or starts but then stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for a maximum of 15 seconds. This clears the extra gasoline from the engine. If the engine still won't start or starts briefly but then stops again, repeat Step 1 or 2, depending on the temperature. When the engine starts, release the key and the accelerator pedal.

The electrical cord is located on the driver's side of the engine compartment. 3. Plug it into a normal, grounded 1IO-volt AC outlet. 2-22
