The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance. Communicating these specific symptoms to your technician can save diagnostic time.

    I stopped to visit a friend and an hour later the engine turned over, but would not start. It did start a half hour later and I drove it to my shop. The owner told me it was probably the crankshaft sensor. It was. It cost about $300 to fix with parts and labor.
