Can a crankshaft position sensor keep car from starting?

Yes, a crankshaft position sensor can keep a car from starting. The crankshaft position sensor is responsible for sending a signal to the engine's computer about the position of the crankshaft. This signal is used by the computer to control the timing of the fuel injection and ignition systems. If the crankshaft position sensor is not working properly, the engine will not be able to start.

Here are some symptoms of a faulty crankshaft position sensor:

* The engine cranks but does not start.

* The engine stalls intermittently.

* The engine runs rough or misfires.

* The check engine light is illuminated.

If you are experiencing any of these symptoms, it is important to have your car diagnosed by a qualified mechanic. A faulty crankshaft position sensor can cause serious damage to your engine if it is not repaired in a timely manner.
