Recommended Procedure

WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Verify there is fuel in the tank and battery voltage at the fuel pump. With the key ON and engine OFF use a digital multimeter (DMM), and measure the voltage between the fuel pump power and ground circuits. Battery voltage is present for approximately 30 seconds after the key is turned to the ON position. If no voltage is present, refer to PINPOINT TEST MA - FUEL PUMP CONTROL - LOW PRESSURE PUMP .

Disconnect the fuel line on the outlet side of the fuel conditioning module. Install the Fuel Line Adapter 310-159 or equivalent and the Magnehelic Gauge® 0-200 kPa (0-30 psi) Bar (part of DSL ENG Pressure Test Kit 014-00761 or equivalent). Measure the fuel pressure with the key in the ON position and the engine OFF. If fuel pressure is below 20.7 kPa (3 psi), go to the next step to verify no restriction.
