Where is the fuel pump relay located on a 1994 Ford Taurus?
Where is the fuel pump relay located on a 1994 Ford Taurus?
1994 ford taurus fuel pump relay is in the constant control relay box sitting on top of the radiator fan shroud below the plastic “cover” that has labels for belt diagram, engine size etc. Center of car.
Why does my Ford pickup have a green relay?
You’ll be able to find out if the fuel pump relay, or the fuel pump Inertia Switch, or the fuel pump is the cause of the No Start Condition on your Ford car or pickup. If your fuel injected Ford pickup, van, or car still has the Ford relay, this bad boy will be a green color (like the one in the image viewer).
How does the fuel pump relay work in a Ford?
The fuel injection computer then grounds circuit 1. This activates the fuel pump relay to pass current from circuit 4 to circuit 3. Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate.
What does a green fuel pump relay look like?
If it has already been replaced with an after-market one, this relay won’t be green, but will have a gray body. The following tutorial may be of help: How To Test The Fuel Pump (Ford 4.9L, 5.0L, 5.8L) (at: troubleshootmyvehicle.com ).
When is the fuel pump relay turned on?
The fuel pump relay is activated whenever the ignition is turned on. A fuel pump relay functions primarily to maintain a consistent voltage supply to the fuel pump. The ignition or powertrain control module (PCM) usually controls the fuel pump relay.
Is the fuel pump relay controlled by the PCM?
Consequently, the fuel pump relay is usually controlled by, the ignition or powertrain control module (PCM). As a result, when switched on, the fuel pump relay; will provide current to the fuel pump, so that it may function. Therefore, any faults with it, can cause fuel pump issues.

How is circuit 3 connected to the fuel pump?
Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate. Before this voltage reaches the fuel pump, it has to go through the fuel pump Inertia Switch first. If the Inertia Switch has been tripped, it will ‘open’ the circuit and the voltage will not reach the fuel pump.
Why does my Taurus fuel pump not start?
One symptom of a fuel pump problem is a non-starting vehicle. The Taurus contains a fuel pump shutoff switch. The engine fails to start if the switch has been activated. Resetting the switch restores power to the fuel pump. If the reset does not resolve the problem, then perform further diagnosis.
Can a fuel pump problem cause a car to not start?
One symptom of a fuel pump problem is a non-starting vehicle. The Taurus contains a fuel pump shutoff switch. The engine fails to start if the switch has been activated. Resetting the switch restores power to the fuel pump.
What makes up the fuel system in a 1999 Ford Taurus?
The fuel system in a 1999 Ford Taurus consists of a fuel pump, fuel supply manifold, throttle body, pressure regulator, fuel filter and fuel lines. A faulty Taurus fuel pump disrupts normal engine performance. Knowing the symptoms of a bad fuel pump makes diagnosis and repair easier.
Where is the fuel pump on a 1998 Ford Taurus?
The fuel pump for the 1998 Ford Taurus is part of a module that’s inside the fuel tank and includes the fuel sending unit. Unlike many models that use this type of module, you can easily disconnect the fuel pump and replace it rather than replace the entire module.
Where is the fuel cutoff switch located on a 2004 Taurus?
Ford Taurus Questions – where is the fuel cutoff switch located on 2004 taurus. – CarGurus where is the fuel cutoff switch located on 2004 taurus. If your vehicle is a sedan, the fuel pump shut-off switch is located on the right side of the trunk behind the trunk liner.
How do you remove a fuel pump from a tank?
Lift the long, curved fuel pump module out of the tank until you can reach its locking tabs, then squeeze the tabs together with your fingers and remove the fuel pump module from the tank. Pull off and discard the lock ring gasket from the top of the module.
How do you connect the fuel tank to the car?
Connect the fuel tank to the car in the reverse order of removal–raise it back into position with the floor jack, connect the fuel lines and electrical connectors strap it in place with the straps. Lower the car and reconnect the battery cable. Connect the fuel pump inertia switch and press its reset button to energize the pump.
