## NHTSA's summary

This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that may have a no crank concern. Technician will need to check the valve train for movement when the engine is cranked. If the valve train is not moving while the crankshaft is moving the front cover will need to be removed to inspect for a sheared cam sprocket locator pin. If the cam sprocket locator pin has sheared, replace the engine assembly. If the valve train is rotating during inspection, disconnect the Camshaft Position sensor and check if the engine will start. If the engine starts front cover will need to be removed to inspect for a sheared cam sprocket locator pin. If the cam sprocket locator pin has sheared, replace the engine assembly.
