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.

    It suddenly lost power during 68 mph on I-10. All indicators lit up and steering wheel engaged in lock position. The other time, it lost power after running over a bump. After performing a diagnosis and online information, it could be a malfunctioned Crankshaft Position Sensor. Just had it replaced and tested for 30 miles with no problem. Still wait to test another long trip this week.
