Systems for efficiently starting an engine of a hybrid electric vehicle are provided. An example of a system comprises a first processor and a second processor. The second processor is configured to determine when to start an internal combustion engine, cause energy to be supplied from an energy storage device to a generator/motor to cause the generator/motor and crankshaft to rotate to at least a hold speed, transmit a first instruction to a first processor when determining that the internal combination engine should be started. The first processor does not supply fuel to at least one cylinder of the internal combustion engine in response to the first instruction. The second processor is configured to transmit a second instruction to the first processor after a variable period of time has elapse after the generator/motor or crankshaft has reached at least the hold speed.
