How do you tell if your injectors are leaking?
How do you tell if your injectors are leaking?
Symptoms of Leaking Fuel Injectors:
- Hard Starting when engine is hot.
- Increased Fuel Consumption.
- Rough Idle.
- Fuel odors inside and around the car.
- Poor Emissions.
- Oil thinning, which can lead to catastrophic engine failure.
- Hydro-lock, which can lead to catastrophic engine failure.
What causes fuel injector to leak and cause hard starting?
Leaking fuel injector can be cause of hard starting. This is because the fuel rail pressure has dropped and fuel has leaked into the manifold and causes the spark plugs to become flooded. Both top feed and side fuel injectors make use of O-rings to seal between the fuel injector and fuel rail.
Why does my fuel injector make a bad sound?
Rough idling/engine stalling – uneven supply of fuel during idling can cause RPM to fall too low and result in stalling. For example have a listen to this bad fuel injector sound: In addition to performance issues, you will also have to deal with:
What are the symptoms of a clogged fuel injector?
Dirty, clogged, blocked, leaking or generally faulty fuel injectors have the following symptoms: Engine stutter, hesitation, stumbling – without the proper air/fuel mixture, the combustion inside the cylinders is impeded. Engine misfire – poor air/fuel mixture in the cylinders can cause an incomplete combustion event.
Can a cracked fuel injector cause an engine fire?
Any external fuel injector leaks such as a cracked fuel injector body or bad fuel injector O-rings can cause an engine fire at any given time. At engine shutdown the fuel pressure should maintain operating pressure or just below that for a substantial period of time.

How can I tell if my fuel injector is leaking?
Once you notice any injector that is spraying excess fuel, it is an indication that the said injector is leaking. For a clear visual presentation, watch this video. Just like checking for fuel leaking injector, you have to clearly look at the injector areas to see if there is any leak.
Why does my fuel injector make a sharp sound?
Fuel injectors make a sharp clicking sound, when they are functioning properly. So, the absence of this sound can indicate, a problem with an injector. In general, fuel injectors are hard wearing and with a little care, can often last; the life of the engine.
Any external fuel injector leaks such as a cracked fuel injector body or bad fuel injector O-rings can cause an engine fire at any given time. At engine shutdown the fuel pressure should maintain operating pressure or just below that for a substantial period of time.
