A pump health assessment system and a method for providing a pump health of a pump is disclosed. The method includes: determining that there is an imbalance in the pump; increasing pump flow from the pump; measuring a rail pressure of a fuel rail; determining if the rail pressure is substantially equal to an expected rail pressure profile; and in accordance with a determination that the rail pressure is not substantially equal to the rail pressure profile, outputting an indication of pump damage.
