If your car doesn’t start try adding Some starter fluid into The fuel pump. Make sure that your airbox is off while adding the fuel pump. The next thing to check for is the inertia switch which takes place in the trunk of a car. Make sure that the red button is pressed all the way down. Pop it back up and push it all the way back down to restart it.. This which is designed to cut the power to the fuel pump in case of an accident. Sometimes it gets jammed if it hit a large pot hole etc.

If the car has been sitting around to long try this...[Cars are not meant to be sitting around. They are meant to be used because parts can get rusty. So Fluids start building up in the engine and the transmission]
Try to get under the hood and check the engine oil. make sure that there is no leaves or animals or debris in or under the grill of the car. This can start fire hazards when starting your car and can heat up easily!
Remove the spark plug and add fogging oil to lubricate the walls. If the spark plug is cracked get a new one.
