A failing fuel pump can trigger the check engine light, but not always. When fuel pressure is too low or inconsistent, the engine computer may detect misfires or a lean fuel mixture and turn the check engine light on, along with related trouble codes. However, some pumps fail without setting a clear code, so the light alone is not a perfect indicator. Proper testing of fuel pressure and the electrical circuit is needed to confirm a pump problem.
