Yes, if the eighth digit is a "W", then you have CSFI.
These are the steps that I would take:
1) Make sure that the battery is good and completely charged.
2) Change the fuel filter.
3) If it's still low, I would then check the pressure at the fuel filter to rule out a faulty Fuel Pressure Regulator
4) If it is low at the filter, then I would move on to the pump.
