What job does the fuel injector perform in the fuel system?
What job does the fuel injector perform in the fuel system?
When the throttle valve opens, your fuel injector sprays fuel to mix with the air and then enters the engine’s combustion cylinders. Fuel injectors can become dirty and clogged over time, which will lead to poor performance, bad gas mileage, and even dirty exhaust emissions.
When is it time to replace the fuel injector?
When to consider replacing a fuel injector: Rough idle, loss of power, or misfiring. Odor of raw gas or visible leaks. Check engine light. Major engine repairs, engine replacement, or lengthy storage.
How does a fuel injector work in an engine?
Fuel injectors are small parts within your fuel injection system that are designed to take fuel and spray it into the intake manifold in your engine at the right angle. In doing so, it allows the fuel that is introduced into your intake manifold to mix together with the right amount of air.
How to diagnose a fuel injector problem?

How do you know when to replace a fuel injector?
Another effective test is to measure the pressure loss in the fuel rail when each injector is fired and pulses for a set period of time. Use an electronic injector pulse tester for this. As each injector is energized, a fuel pressure gauge is observed to monitor the drop in fuel pressure.
What causes a fuel injector to not set a code?
A shorted or open fuel injector solenoid, or a shorted or open coil will usually set a code. Consequently a dirty or weak fuel injector or a weak coil probably won’t set a code. Bad spark plug wires are a common cause of misfire codes.
How much does it cost to replace a cylinder 2 fuel injector?
