The Porsche Cayenne 3.6 engine cannot be started after overhaul, and there is no fuel pressure.

1. gasoline pump failure. Similar to the exhaustion of oil, the damage of gasoline pump can also lead to fire. When the ignition is started, the starter works normally, but the car does not start. Check the oil pressure in the gasoline pipeline. The gasoline pump must be broken.

2. Starter failure. Starter damage can also lead to ignition failure, similar to the battery dead, ignition does not respond.

3. There is too much carbon in the throttle. Without stepping on the accelerator, the throttle leaves only a little gap for air to pass through. If there is too much carbon in this gap, it will block the gap, causing air to pass, so it will not catch fire. At this time, in the process of striking the fire, you can get on the bus smoothly by stepping on the accelerator a little.

4. The crankshaft position sensor is faulty. This sensor monitors the position of the crankshaft to determine when to ignite. It is also called a speed sensor. If it is damaged, the engine computer can't receive the speed signal when igniting, so it won't control the spark plug to ignite, because the computer doesn't know you are igniting at all.
