Do fuel injection engines have spark plugs?

Do fuel injection engines have spark plugs?

Modern engines with smart gasoline direct injection need spark plugs perfectly geared to the specific requirements of each combustion chamber.

What happens when a fuel injector is faulty?

Engine vibrates – When a fuel injector is faulty, the corresponding cylinder will be affected, and thus, it won’t be capable of firing. What this means is that while in motion, your engine is likely to hiccup, or vibrate in a bid to conclude each cycle without the needed fuel.

What causes a spider fuel injector to misfire?

This case study will help you to diagnose a ‘Spider’ fuel injector that is stuck open due to the PCM having fried and causing one of two things: A misfire condition or an engine hydrolock condition (a no crank condition caused by gasoline filling up an entire engine cylinder).

What causes no injector pulse when engine is craking?

When these fuses blow, the system they support stops working, and the engine stops running. As a result, there is no injector pulse while craking.

What kind of fuel injector does a 4.3L engine use?

This system used on all 4.3L, 5.0L, and 5.7L engines from 1996 to present. This ‘Spider’ assembly has either 6 or 8 individual fuel injectors that feed 6 or 8 nylon fuel lines. The CSFI system does use a MAF sensor.

Where is the fuse for the fuel injector located?

Blown injector circuit fuse Bad fuel injector power relay A fault in the wiring harness to the injectors So, the injector fuse and relay are usually located; in the relay box or power distribution center in the engine compartment. Fuses are used to protect various electrical circuits, while supplying power to components.

When these fuses blow, the system they support stops working, and the engine stops running. As a result, there is no injector pulse while craking.

How does the engine control unit control the injector pulse?

Question: What controls the fuel injector pulse? Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line

How do I know if I have a bad coil or bad fuel injector?

You would simply unplug the injector, plug the noid light into the harness for the injector, and when the engine is started, will show a light when the pulse to the injector is present.
