P0005 - is there anything in the book? also according to rock-auto it is a electrical connectionWhen you say "valve", do you mean "switch"? Location for 5.4-liter V8. The 2002 model year features a fuel pump cut-off switch designed to inhibit the delivery of fuel to the engine if an accident occurs. The fuel pump cut-off switch also has the potential to disengage the fuel pump after a hard jolt, preventing the engine from running.
Reset the fuel pump cut-off switch by pressing the small, round button, located near the passenger-side kick panel, underneath the right-side portion of the glove compartment.
What is the code? P_ _ _ _ ?
Thank you MikeMy info does not show that code to apply to that vehicle. From my experience, that truck with 5.4L has no device that meets that code description.
From The Web...
P0005 is a generic type of of diagnostic trouble code which indicates that the Engine Control Module (ECM) detects a problem with the fuel pump shut off solenoid. This code is rarely seen as it does not pertain to any particular make or model of vehicle.
The fuel pump shut off solenoid is an electromagnetic switch that allows or blocks the passage of fuel from the fuel pump to the engine, according to the position of the ignition switch. When the ignition switch is turned with the ignition key, a signal is sent to the fuel pump shut off solenoid, which protrudes or retracts a shaft that starts or stops the flow of fuel to the engine accordingly. The shaft pops out within the fuel passage to block the flow of fuel if the ignition is off, or the switch is defective.
