Abstract

In a fuel injection pump with a housing, a metering pump and an injection adjuster for the metering pump, in which the injection adjuster has a piston that is acted upon by a restoring spring, the starting performance of the internal combustion engine supplied by the injection pump is to be improved by providing a starting spring which acts on the piston and acts counter to the restoring spring.
