I'm sure your mechanic informed you that this is a fuel pump related issue like the fuel pump, fuel pump relay or inertia switch? If you search the forums, you will see that there have been MANY people that have replaced the fuel pump in this car.

Does the car start and run? Inertia fuel shutoff (IFS) switch may need to be reset.

  • Inertia fuel shutoff (IFS) switch needs to be reset.
