Abstract
Methods and systems are provided for relieving pressure from a compression locked engine. The engine may be compression locked during an engine start attempt due to operator application of a manual transmission clutch at or around the time of a first combustion event of the engine start. A direct injector of the compression locked cylinder is commanded open to relieve the pressure into the fuel rail.
