Why do you need a wiring diagram for a fuel injector?
The diagram provides visual representation of the electrical structure. However, this diagram is a simplified variant of the structure. It makes the procedure for assembling circuit simpler. This diagram gives advice of circuit’s components in addition to their own placements.
What do the traces on a fuel injector mean?
According to earlier, the traces in a Fuel Injector Wiring Diagram signifies wires. Occasionally, the wires will cross. But, it doesn’t mean connection between the wires.
What does black dot mean on fuel injector wiring diagram?
According to earlier, the traces in a Fuel Injector Wiring Diagram signifies wires. Occasionally, the wires will cross. But, it doesn’t mean connection between the wires. Injunction of 2 wires is usually indicated by black dot at the intersection of two lines.
How are fuel injectors attached to the fuel rail?
Learn to test and analyze automotive fuel injector circuits from a wiring diagram perspective. Fuel injectors are attached to the fuel rail. It is very time consuming to detect and prove a clogged fuel injector. The technician needs to disassemble the fuel rail, de-activate the fuel pump and perform lengthy tests to prove the fault.

How many pins are on the harness and fuel injector?
The White (7 pin) connector wasn’t detailed on Josh’s diagram, as it seemed to just connected to standard engine connections. However, for some reason he’d relocated all but one of the pins to different parts of the connector. I found it much easier to remove the male pins on the other side of the harness to make the connectors match.
Where does fuel injection take place in a 1972 car?
On 1972 models, all injection takes place behind closed intake valves. Fuel is effectively stored in the intake ports of cylinders until the intake valve opens. Figure 6 shows a cutaway of an injector. The control unit sends an electrical pulse to the magnetic winding in the injector.
How does a fuel injector open and close?
The control unit sends an electrical pulse to the magnetic winding in the injector. The pulse causes the needle to move off its seat and inject fuel. Then the return spring reseats the needle at the end of the pulse. The time the injector is open varies from about 2-10 milliseconds (0.0020.010 seconds).
