1. An engine control module, comprising:
- an engine starting module that communicates with an electric motor to operate an internal combustion engine including M fuel injectors, and that determines whether manifold pressure is below a manifold pressure threshold; and
a warming module that communicates with said M fuel injectors to inject fuel into N of M said fuel injectors when said manifold pressure is less than said manifold pressure threshold,wherein N and M are integers and N is less than M.

Abstract
An engine control module includes an engine starting module that communicates with an electric motor to operate an internal combustion engine including M fuel injectors and that determines whether manifold pressure is below a manifold pressure threshold. A warming module communicates with the M fuel injectors to inject fuel into N of M the fuel injectors when the manifold pressure is less than the manifold pressure threshold. N and M are integers and N is less than M.
