Q: car wont crank or start

Hi There, Depending on whether or not the vehicle will turn over will determine what the next step should be. If the engine does not turn over, I would recommend checking all connections related to the battery and check to be sure the starter relay is producing power to the starter. If the engine does turn over, this may be related to a spark or fuel supply problem. Things like ignition coils, crankshaft position sensor, spark plugs, spark plug wires or ignition module are all components that help to create spark and control ignition timing which may cause the motor to not produce spark or the correct timing needed to ignite the fuel in the motor. In the case of a fuel delivery problem, this may be related to low fuel pressure, faulty or dirty fuel injectors, a faulty or dirty idle air control valve (this relays information about air intake to the computer which makes fuel adjustments), or potentially a faultyfuel pressure regulator要么燃油泵。燃料输送问题通常不允许将适当的燃料传递到气缸中，从而导致瘦燃料状况，这可能会导致转火或仅导致电动机由于燃料饥饿而无法启动。在某些情况下，可能向电动机提供过多的燃料，从而导致电动机过多，无法将其引入比燃烧的速度更快。这导致电动机充满了太多燃料，也导致其无法正常运行。上述任何可能性都可能在适当的空气/燃油比中造成不平衡，这会导致电动机运行非常粗糙或根本不延伸。我建议您让您的机电专家来您的位置诊断和检查您的车辆。万博体育入口
