A Mercedes E420 fuel injector is a crucial component of the vehicle's fuel delivery system. It's responsible for spraying fuel into the car's engine in a mist-like form, helping to ensure optimal performance and efficiency.
This device operates under high pressure conditions to precisely distribute fuel directly into the combustion chamber. Without the fuel injector, the Mercedes E420 would not be able to run smoothly or efficiently, proving the critical role it plays in vehicle operation.
Signs of Faulty or Worn Mercedes E420 Fuel Injector

Replacing Mercedes E420 Fuel Injectors
- Start by disconnecting the negative battery cable to avoid any electrical issues.
- Locate the fuel rail, which houses the fuel injectors. It's usually located near the top of the engine.
- You'll need to relieve pressure from the fuel system. This can typically be done by loosening the fuel cap and using a wrench to open the fuel rail's pressure relief valve.
- Once the pressure is relieved, you can disconnect the fuel supply line from the fuel rail.
- Next, remove the bolts securing the fuel rail in place. Be careful not to lose these bolts as you'll need them for reassembly.
- With the fuel rail now loose, you can gently lift it off the engine. The fuel injectors should come with it.
- Now, locate the faulty fuel injector on the fuel rail. They are typically attached via clips or wiring harness.
- Gently remove the faulty fuel injector from the fuel rail and replace it with the new one. Make sure to secure it properly.
- Reattach the fuel rail to the engine and secure it with the bolts. Connect the fuel supply line back to the fuel rail.
- Double check all connections and make sure everything is securely fastened.
- Reconnect the negative battery cable.
- Finally, start your car and let it run for a few minutes to ensure the new injector is working correctly. Watch for any leaks or other issues before taking your vehicle out on the road.
