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. Damaged O-Ring Causing Injector Leak If it breaks, then fuel can leak out, over the engine.
What causes fuel injectors not to Pulse?
The nature of the cause of no injector pulse is that there is no power input. The three main factors that lead to that condition are blown injector fuse, bad injector electrical relay, and bad wiring. Typically, fuses and relays will be located in the junction box in the engine compartment.
Where does fuel injectors get power from?
Fuel injectors operate though the brief charging of a solenoid and subsequent opening of a valve. The opened valve allows pressurized fuel to be pushed through the fuel injector nozzle into a fine spray. The solenoid is engaged when a 12-volt current is provided by the electronic fuel injection system.
How do I know if my fuel injectors are getting power?

Is there a fuse for fuel 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. They help the fuel pump, fuel injection and computer systems; from suffering a short circuit.
Where is the fuel injector relay?
In most vehicles, the relay is located in the large fuse box in the engine compartment.
How do you check an injector with a multimeter?
What's ignition Control Module?
What exactly is an (ICM) Ignition Control Module? An ICM is nothing more than a switch that turns the ignition system “On” or “Off”. Inside of the distributor there is a sensor that sends out a signal to the ICM, which is then used to fire up the ignition coil that will create enough energy for the spark plugs.
How do you bypass injector resistor box?
One wire is power going into the resistor, the rest are power wires out of the resistor to each injector. To bypass the resistor what you need to do is connect all of the wires together that were going to the resistor. This will send full 12 volts to all of the injectors.
Can you jumpstart a fuel injected car?
The most common method to start such a vehicle engine is to jump start it. A fuel pump is used for fuel injection. It can be mechanically driven or is electrically driven. If electrical then the same problem may arise which the battery cannot turn the pump because it is heavily discharged.
How do you test a fuel injector on a car?
Answer: The easiest way is to listen to the injector with a mechanic's stethoscope or a length of hose. You should hear a clicking sound as the injector's valve opens and closes. However, if the injector is clogged, even if it's working it'll not spray any fuel.
