Troubleshooting: The vehicle's fuel injection system is the only fuel-injected L-shaped Terra-Ronique system, which is the early product of BMW. BMW's new system, in addition to fuel injection control, but also for ignition and idling speed control, and by a computer centralized control, known as DME. It should be said that the car's control system is a rare system.
    (2) check the fuel pressure, do not start the engine when the 280KPa, the normal idle when the reference value of 220KPa, it should be said is good; ④ temperature is not good; There is no problem with the cold start ejector control when the switch is controlled. As for the compression pressure of the engine, the cold start is good, there is no problem after the start of the operation, the mechanical stability, in any case can not say hot start is not good, so also as a good look, no measurement compression pressure.
    From the above inspection results, the normal operation of the engine three elements are no problem, according to the engine should be able to start. However, the engine can not start is the fact that the three elements must have which one element is not good. There is no room for doubt; only the fuel injector only hear the sound of action, and did not see the injection of fuel, the possibility of a short injection time is very large, but the fuel is not the same, There is a need for further investigation.
