摘要：
Methods and systems are provided for enforcing a minimum fuel lift pump commanded voltage that is determined as a function of commanded lift pump pressure and fuel flow rate. The minimum fuel lift pump voltage is applied when the commanded voltage is lower than the minimum voltage. The approach reduces engine stalls induced by ingestion of fuel vapors at an injection pump coupled downstream of the lift pump.
