Is Your Scion xD's Fuel Injector Failing?
A bad fuel injector can cause noticeable problems with your engine's performance. 🎬 Learn how to test your fuel injector using a multimeter. Because the Scion xD has a reliable engine, these issues often stand out. Ignoring them can lead to worse fuel economy, failed emissions tests, and even damage to other parts of your engine or exhaust system.
Symptoms of a Bad Fuel Injector:
- Rough Idle: Your car may shake or vibrate when stopped at a light.
- Engine Misfires: You might feel a stumbling or hesitation from the engine, especially under acceleration. This often triggers the Check Engine Light with codes from P0300 to P0304.
- Poor Fuel Economy: A leaking or inefficient injector can cause your car to use more gas than usual.
- Hard Starting: If an injector leaks fuel into the cylinder when the car is off, it can create a "flooded" condition that makes the engine difficult to start.
- Gasoline Smell: A physically cracked or poorly sealed injector can leak fuel, creating a dangerous fire hazard and a strong gas smell.
No Known Recalls or TSBs
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Scion or Toyota for widespread fuel injector failure on the 2008-2014 Scion xD. Problems are typically due to age, mileage, or fuel quality.
Choosing the Right Aftermarket Fuel Injector
When replacing a fuel injector in your Scion xD, you have a choice between expensive OEM parts and more affordable aftermarket options. For a vehicle of this age, a quality aftermarket part can offer the best balance of price and performance.
Here’s a look at the brands available:
- Standard Ignition (SMP): A well-regarded aftermarket manufacturer. They invest in testing to ensure their injectors match the performance of the original parts. They are generally considered a reliable choice by mechanics and DIYers.
- Beck Arnley: This brand specializes in parts for import vehicles and aims to provide parts that meet OE specifications for fit and function. They are a reputable option for Asian vehicles like your Scion.
- GBR Fuel Injection: Information on this specific brand is limited in public forums and reviews. It may refer to GB Remanufacturing, which focuses on remanufactured parts. When considering this brand, it is important to verify if the part is new or remanufactured.
OEM vs. Aftermarket Quality
The original injectors in your Scion are made by Denso. While OEM is always a safe bet, the cost can be very high, with a full set costing nearly $900 in parts alone. Quality aftermarket brands like Standard Ignition and Beck Arnley provide a cost-effective alternative without a significant compromise in performance for a daily driver. For a critical component like a fuel injector, it's best to avoid generic, unbranded options.
How Much Does a Scion xD Fuel Injector Replacement Cost?

Frequently Asked Questions
Should I replace all four fuel injectors at once?
It is highly recommended. Fuel injectors are wear items that operate under the same conditions. If one has failed due to age or clogging, the others are likely not far behind. Replacing them as a set ensures balanced fuel delivery to all cylinders, which is critical for smooth engine operation and performance.
Is replacing a fuel injector a good DIY job?
For someone with moderate mechanical experience, yes. The process involves depressurizing the fuel system, removing the fuel rail, swapping the injectors, and reassembling. It's important to be careful, work in a well-ventilated area, and have a fire extinguisher nearby since you are working with gasoline. Always use new O-rings and lubricate them with a little oil or gasoline before installation to ensure a proper seal.
What is a P0301 code?
A P0301 code means there is a misfire detected in cylinder #1. The codes follow cylinder order, so P0302 is for cylinder #2, and so on. While a failing fuel injector can cause this, it can also be caused by a bad spark plug or ignition coil. It's common to swap coils between cylinders to see if the code follows the coil before condemning the injector.

Basic hand tools like a socket set and pliers are all that's typically needed. No highly specialized tools are required for the Scion xD. However, a fuel line disconnect tool might be helpful, and it's crucial to relieve fuel system pressure before starting. This can often be done by pulling the fuel pump fuse and cranking the engine a few times.
