The only way to truly tell is to place a fuel pressure gauge on both sides of the line and get a reading from both. They are both going to cause the same hesitation at high speed and difficulty starting. A bad fuel pump will have low pressure on both sides. How do you tell them apart? A clogged fuel filter will have high pressure on its input side and low pressure on its output side. This makes telling if you have a bad fuel pump vs bad fuel filter very challenging. It Could Also be Your Focus’s Fuel FilterĪ fuel pump that is going out is going to feel the same as a bad fuel filter.

Here’s a great youtube video on how to test a fuel filter: 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. If any of these things aren’t present, the engine won’t turn over at all. If the fuel pump has completely failed, the engine won’t start at all.Īt the most basic of levels your Ford Focus needs three things to start: Air, fuel, and spark. Often it’ll be bad spark plugs, or a bad coil pack. Instead, we’d recommend taking a look at the ignition system first. If your Focus is difficult to start, a bad fuel pump would probably not be the place to start looking, especially if you are’t getting a fuel related trouble code. This because there’s not enough fuel pressure to properly atomize the fuel as it enters the combustion chamber. One of the best indicators of a clogged fuel pump is going to be that the your Focus is difficult to start. If you get P0420 or P0430 trouble codes with a scanner, it very well may be the catalytic converter causing these symptoms. If you are unsure, check out this article on troubleshooting catalytic converters. A bad catalytic converter will not feel as jarring. Both conditions will make the motor feel like it is running out of wind when you hit the gas. Now, a bad fuel pump can also feel a heck of a lot like a bad catalytic converter. That’s what it feels like with a bad fuel pump. Typically, if you are heading up a hill (or accelerating) the engine may start to feel like it is just running out of steam. The only way that you are going to know that your Focus’s fuel pump is going out is that it is no longer providing enough fuel pressure to keep the engine running under a heavy load, or at high-speed. It’ll sound like a low frequency buzzing sound. Keeping an open ear can save you from getting stuck somewhere with a bad fuel pump.
The whining sound can indicate that the fuel pump is going out before there are any performance based issues. One of the most common signs that a fuel pump is going bad is a whining sound. Here are the most common symptoms of a bad fuel pump in your Ford Focus: Also, the symptoms are almost exactly the same as bad/clogged fuel filter. The real issue with diagnosing a bad fuel pump is that it resembles many other vehicular issues in terms of symptoms.

Sometimes when there is low fuel pressure, you may also get an oxygen sensor related trouble code as well. Any trouble codes that exist could be a clue. This trouble code detects that the fuel rail/system pressure is too low. The engine may throw a P0087 trouble code. Before taking anything apart, check to see if your engine’s computer has any trouble codes saved in it. There are physical signs that you can feel when your Focus’s fuel pump is going out. The bad news is that they cost a lot in terms of labor to repair and replace. The good news is that fuel pumps are inexpensive. While being in the fuel tank makes the pump more reliable, it also makes it a lot more difficult to get to. 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. In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail(s). With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all. Without gas your Focus will not run at all.
If your Ford Focus’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. One of the worst problems that can happen to a vehicle is a bad fuel pump.
