What happens if my Subaru Forester fuel pump goes bad?
If your Subaru Forester’s fuel pump goes bad, no fuel (or not enough fuel depending on whether or not it’s out all the way) can enter the engine. Without gas your Forester will not run at all. With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all.
What are the symptoms of a bad fuel pump?
Here are the most common symptoms of a bad fuel pump in your Subaru Forester: One of the most common signs that a fuel pump is going bad is a whining sound. The whining sound can indicate that the fuel pump is going out before there are any performance based issues. Keeping an open ear can save you from getting stuck somewhere with a bad fuel pump.
What to do if your Subaru won’t refuel?
The vehicle should first be checked for obvious problems, such as crushed or kinked hoses, misrouted hoses or broken components. If nothing is found, go to the gas station and confirm the condition. Should you encounter a Subaru vehicle that won’t refuel or causes the gas nozzle to shut off prematurely, here are some tips to aid diagnosis.

What to do if your fuel pump goes bad?
If there’s been zero warning that the fuel pump could be going bad (hesitation, difficulty starting, etc) then it should not be automatically assumed that the fuel pump is at fault. Here’s a great youtube video on how to test a fuel filter:
Where does the fuel pump go in a car?
In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s). It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do.
When to turn on fuel pump in Subaru Outback?
The pump is only on when the engine is running, the key is in start whir whir whir, and for a second or two when the key is moved from acc to run (so that would be a click). Based on that the relay shouldn’t be clicking continually (i.e. every 1/2 second) with the ignition set to run (without the engine running) should it?
Why does fuel come out of the fuel pump?
There is a relay under the dash somewhere that the ECU energizes, the relay in turn energizes the fuel pump. Sometimes that relay goes bad. One post I saw the output transistor in the ECU had gone bad so the person replaced the transisitor. Maybe your fuel filter is just plugged up? Does fuel come out if you remove the fuel filter supply line?
How can you tell if your fuel pump is failing?
If you ignore all of the other warning signs of a failing fuel pump, it will eventually fail completely. Once your fuel pump has finally given up the ghost, no fuel will reach your engine. You may hear your spark plugs firing when you try to start your car, but without fuel, the engine won’t be able to turn over.
What happens if your fuel pump is failing?
The fuel pump feeds fuel to the engine at a reliable rate; without this pump, your fuel would just sit in your tank, useless and inert. If you’re attentive, you can catch the symptoms of a failing fuel pump and have it repaired or replaced before it leaves you stranded on the side of the road.
How does a fuel pump work on a gas gauge?
The fuel pump module includes the fuel sending unit, used by the gas gauge to detect and display fuel level. https://www.flickr.com/photos/3ndymion/33556245572. The gas gauge is a relatively simple circuit, but its simplicity means each component is essential to its function.
Why is the fuel pump in the fuel tank?
It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to. The good news is that fuel pumps are inexpensive.
