A Practical Guide to Fuel Injectors for the 2000-2002 Chrysler Neon
Solve common engine problems like rough idle and poor gas mileage by understanding when and how to replace your Neon's fuel injectors.
- A rough idle and a cylinder-specific misfire code (e.g., P0301) are the strongest indicators of a bad fuel injector on a Neon.
- For best results and to avoid future repairs, replace all four fuel injectors as a set, not just the one that failed.
- Always use the new O-rings that come with your injectors and lubricate them with clean oil to prevent fuel leaks.
- Ensure you buy standard injectors for the 2.0L engine, as high-performance SRT-4 injectors will cause problems.
Is Your Neon's Fuel Injector Failing?
When a fuel injector starts to go bad on a 2000-2002 Chrysler Neon, the signs are usually easy to spot. The injector can get clogged with deposits from fuel over time, or the electronic part inside can fail. It might get stuck open, dumping too much fuel, or get stuck closed, starving a cylinder of fuel. Watch out for these common symptoms:
- Rough Idle and Misfires: This is the most frequent sign. Your engine might feel shaky or sputter, especially when you're stopped at a light. This often comes with a Check Engine Light and misfire codes like P0301, P0302, P0303, or P0304.
- Check Engine Light: A bad fuel injector will almost always trigger the check engine light.
- Poor Fuel Economy: If you notice you're filling up your gas tank more often, a leaking or stuck-open injector could be the cause.
- Hesitation on Acceleration: When you press the gas pedal, the car might stumble or feel like it's losing power because one cylinder isn't firing correctly.
- Hard Starting: Fuel leaking into the engine when the car is off can make it difficult to start.
Choosing the Right Aftermarket Injector
For a vehicle like the 2000-2002 Neon, new aftermarket parts are the most practical and affordable choice. Original OEM Mopar parts are often discontinued or very expensive. Here’s a breakdown of the quality you can expect from available aftermarket brands.
Brand Tiers for Your Neon
- Better (Standard Replacement): Brands like Standard Ignition (SMP) are well-known in the industry and produce parts designed to match original factory performance. They undergo testing to ensure proper spray patterns and flow rates, making them a reliable choice for a daily driver. While any part can fail, these brands offer a good balance of quality and cost.
- Good (Value-Priced New): Brands listed as Replacement are typically new, value-oriented parts. They are an affordable way to get your car running properly again. The quality control may not be as strict as higher-tier brands, but for an older vehicle, they can be a perfectly sensible option for budget-conscious repairs.
- Economy (Remanufactured): Brands like GBR Fuel Injection offer remanufactured injectors. While they are very affordable, be aware that remanufactured parts can sometimes have a higher rate of out-of-the-box issues. It's a trade-off between the lowest price and consistent reliability.
Cost to Replace a Chrysler Neon Fuel Injector

| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Injector (Single) | $40 - $98 |
| Shop Labor | $100 - $225 |
| Total Professional Replacement (Single) | $140 - $323 |
Frequently Asked Questions (FAQ)
Is it hard to replace the fuel injectors on a Neon myself?
No, this is considered a relatively easy job for someone with basic tools. The process involves relieving fuel pressure, unplugging the injectors, removing two bolts that hold the fuel rail, and then swapping the injectors. The whole job can often be done in about an hour.
Should I replace one bad injector or all four?
It is highly recommended to replace all four injectors at the same time. If one has failed due to age and mileage, the others are likely in similar condition. Replacing them as a set ensures all cylinders get a balanced amount of fuel and prevents you from having to do the same repair again in a few months.
Do I need to buy new O-rings?
Yes, but new injectors should always come with new O-rings. Never reuse the old ones, as they become hard and brittle, which can cause a dangerous fuel leak. Lightly lubricate the new O-rings with a little clean engine oil before installation to help them seal properly.
Are there any recalls on Neon fuel injectors?
No, there have been no official recalls issued by the National Highway Traffic Safety Administration (NHTSA) for fuel injectors on the 2000-2002 Chrysler Neon. However, injector failure is a widely discussed issue among owners in online forums.
