What should I do if my fuel injector is not working?
Inspect the injector. And, if you see a small metal clip that looks like a staple pin, use a small flathead screwdriver to remove or depress the clip. Then, with your hand gloves on, grip the injector and work it back and forth while pulling it to remove it from the fuel rail.
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.
Why does my fuel injector keep stalling?
Some of the problems are stalling after you have pressed the accelerator, struggling to accelerate and poor fuel economy. Most of these problems occur due to inadequate air to fuel ratio. Also, any delay could lead to overheating and the engine could stall.
What causes a fuel injector to leak over the engine?
So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.
What should I do if my Ford fuel injector fails?
Fuel Injector Inspection – You can take the injectors out of your Ford and inspect them for damage, dirt or rust. You can start by removing the fuel rails and detaching each injector from the rail. When you remove the injector, there will be fuel that spills out of the rail, so make sure you do not get it on you or the ground.
Where is the fuel injector located in the fuel rail?
At the top O-ring where the fuel injector is located in the fuel rail. (Repairable – replace O-ring) The fuel Injector pintle, ball or disc seat due to damage or corrosion (Not repairable, Discard Injector) The fuel injector body at the top of the fuel injector. (Not repairable – Discard fuel Injector) Test leaking Fuel Injectors.
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.
What happens if you put too much gasoline in the injector?
Either way, you need to find the cause of the gasoline odor and fix it right away before it becomes a big safety hazard. If the fuel injector is spraying too much fuel into the engine cylinder, this will create a surge in the engine causing your acceleration to be much slower.
Hopefully, these tests have allowed you to find the issue with your fuel injectors; but, as mentioned before, it may not be an electrical problem that is causing the injector to malfunction. The next step if the injector resistance is normal would be to remove the injector and test the spray pattern it produces on an injector tester.
How can I tell if my car injector is working?
Any major difference and that injector should be inspected to make sure that it is firing correctly. Tip: You can find the correct resistance for your injectors by searching online or in your vehicle’s repair guide. Step 1: Turn the car on. Turn the key to the second (ON) position for this test.
What happens if the cold start injector leaks?
If the cold start injector leaks at the nozzle, and allows fuel into the intake this will cause an excessively rich mixture. This leak will result in a decrease in fuel efficiency, and in some cases performance and acceleration.
Why is there no pulse from the injector?
Used all original electronics and tbi. New wires, plugs, cap, rotor, fuel filter,etc… have spark, have fuel at the back of the tbi. No pulse at all from either injector?

What causes the fuel injector to become clogged with sediment?
Fuel injectors are the last parts before the combustion chamber in a long list of components that make up the fuel system . Injectors usually last for a long time, but they can become clogged with age or poor fuel quality as the fuel filter fails to pick up all the sediment from the gas tank.

Are there issues with the KTM fuel injection system?
There is quite a bit of chatter going on about issues with the KTM fuel injection systems. While I have not encountered any problems with either the 2011 or 2012 bikes that I have tested, I thought I would look into the issue to see what I could find and hopefully provide some explanation of the system.
What happens when there is no fuel in the fuel pump?
This also verifies that the engine has no fuel pressure. Electric fuel pumps on electronically controlled fuel injection systems need to produce enough “high” pressure to allow the injectors to produce a sufficient spray of atomized fuel into the intake path (or into the combustion chamber in a direct-injection system).
How is the fuel line removed from the fuel rail?
It requires removal of the seat and gas tank. Then the fuel line is removed from the fuel rail with one Phillips head screw. With this apart, you remove the hose camp at the “L” fitting and access the filter. Reinstalling the fuel line to the fuel rail is a little more difficult.
