你好! If, as you say when turning the crankshaft pulley, the engine is not locked, you should look for you initially an electrical problem or starter engine, when the switch is turned when the key is operated with the key, it must continue to verify that it jumps high voltage spark in the spark plugs, if this does not happen, the problem in the ignition system or in the RPM sensor must also be sought, the compression of the cylinders and the compression must also be测量。燃油进料压力。我重复所有这些操作,必须通过具有经验的机械师来完成,否则其他零件可能会恶化,可能不会受到影响,但是被经验不足的操作可能会因为传感器,执行器或同一控制单元(计算机)而被打破。我希望它有帮助,我亲切地向您致意。路易斯。
