What tells you to open injectors?
The ECU is the brain of the operation. It uses engine RPM and signals from different sensors to meter the fuel. It does this by telling the fuel injectors when and how long to fire. The ECU often controls other functions like the fuel pump and ignition timing.
Do fuel injectors fail open?
Fuel injectors are essentially momentary valves that can be clogged in a variety of ways or may simply mechanically fail in the open or closed position.
What happens when fuel injector does not open properly?
Misfiring Engine. The engine misfires when the fuel injector is dirty, clogged or does not open properly. A misfiring engine will cause disturbance to acceleration, reduce fuel efficiency and will also result in loss of power. This requires immediate attention as your engine could also overheat and eventually stall.

Fuel Injector Location The fuel injectors are located on the engine’s intake side, under the fuel rail, which is often located on the intake manifold. If you have a diesel car, your fuel injector is likely located in the cylinder head, but gas fuel injectors are installed on the intake manifold in almost all cases.
What happens when a fuel injector is not working?
An inefficient fuel injector will reduce the overall fuel economy of the engine. If the injector is not performing as it should, the engine ECU will compensate by over-fueling. This causes the engine to run “rich”, leading to more fuel being used than necessary.
Where is the fuel injector located in a diesel engine?
In modern common rail diesel engines, fuel pressures can be over 25,000 psi. Because the injector is seated in the top of the engine cylinder, it is constantly exposed to heat and pressure. This increases the chances of failure over time. Why Causes a Bad Fuel injector? A fuel injector will usually only fail in one of two ways.
Another great way to keep injectors in good health is; to regularly add a fuel injector cleaner to to your fuel tank. Many manufacturers claim that these cleaners, will give your car extra power or increased mpg. They probably won’t, or make much difference, to a car that is running properly.
