Abstract
Systems and methods for restarting an engine are presented. In one example, spark timing during engine starting is adjusted in response to engine speed and a second control parameter. The second control parameter may be correlated with crankshaft or rod degradation. Spark may be advanced from minimum spark for best torque when engine speed is greater than desired and when the second control parameter does not provide an indication of engine degradation.
