  • Toyota Corolla won’t start or stalls unexpectedly and won’t start again. A faulty fuel pump can prevent the car from starting or stall it.
  • check engine light is on. Sometimes a fuel pump fails slowly, which means the fuel pressure and volume slowly degrade. Lack of fuel can cause the engine to run without enough fuel relative to the amount of air, causing your Corolla’s Check Engine Light to come on.
