When was the last time you got fuel? I just attended 2 nights of Advanced training and found out that filling stations are no longer required to filter the fuel coming out of the pumps!!!!!!!

Other than that, it's time to test fuel pressure. Fuel pumps seem to go out like a light bulb. Had my P-up since new in 99. Went to lunch one day fine. Went to leave, no fuel pump.

Relieve the fuel pressure at the schrader valve. While you do that, look for contaminates. After all the pressure is relieved, hook up a fuel pressure gage and see if you come up to proper pressure by turning KOEO and then off. Cycle the key on a few times and then check pressure.
