Fuel Pumps Explained

Your fuel pump sends gas from the fuel tank to the engine. It is inside the fuel tank and pumps fuel to the fuel injectors. These then spray gasoline into the combustion chamber. It has to work perfectly for your car to run smoothly.
A failing fuel pump will cause your car to run rough as the fuel/air mixture will be incorrect. A failed fuel pump won’t send any fuel to the engine, so it won’t start. Read more about how a fuel pump functions and its importance in your vehicle here.
Diagnosing Faulty Fuel Pumps
Interrupting the fuel supply to an engine will cause many issues. These include difficulty starting, lack of power, and intermittent stalling.
This issues can be due to a variety of problems, including faulty fuel injectors, blocked fuel filters, inferior quality fuel and the fuel pump. Odd noises from the fuel tank (located beneath the rear seat) usually mean that the fuel pump is your culprit. A check engine light may also illuminate. Plugging in an OBDII scanner will help narrow down the source of your problems.

OEM Vs Aftermarket
There is no doubt that an OEM fuel pump is going to perform better than an aftermarket item. You may save a bit buying a non-OEM fuel pump, but it may cost you more eventually. OEM fuel pumps offer:
- Perfect fitment
- Correct wiring connectors
- Manufacturer-spec quality
- Toyota’s 12-month unlimited mileage warranty
