Why can't Porsche 997 start?

The reason for the poor start-up may be: 1, the spark plug needs high ignition energy when the cold car is started, and the spark plug electrode gap will become larger after a certain mileage. If the electrode gap exceeds the standard, replace the spark plug in time. 2. When cleaning the throat wall of the throttle intake manifold, the carbon deposit will affect the intake, and the carbon deposit behind the valve will adsorb the fuel and affect the gasoline atomization. If there is carbon deposit, clean the air inlet. 3. Check the gasoline pressure. The low pressure of gasoline pump leads to insufficient oil supply and difficult start-up. In this case, replace the gasoline pump or switch several times to increase the pressure of the gasoline pipe and make it easy to start.

Step 1: Fasten your seat belt and insert the key into the keyhole. Turn the key until acc stops, and wait for about 2-3 seconds, so that the contact of the main power relay is firm, and the first part of the equipment that needs to be powered on can be powered on. Continue to turn the key to on (if the key does not turn, it is likely that the steering wheel is locked, just turn the steering wheel slightly and twist at the same time), then stop waiting for 6- 10 seconds to engage the oil pump relay. Start the engine, and then observe whether the indicator is normal.
