What to do if your fuel injector is stuck in the manifold?
Finding out that your injectors are stuck in the fuel rail or manifold can be a real facepalm moment — which, in itself, can prove far more painful than the process of breaking the injector loose. Check around the injector for any metal clips or screw-on retainers that might be holding it in place.
How does a diesel fuel shut-off solenoid work?
Overview of Diesel Fuel Shut-Off Solenoids. A solenoid valve is an electromechanical valve controlled by an electric current. The electric current runs through a solenoid, which is a wire coil wrapped around a metallic core. A solenoid creates a controlled magnetic field when an electrical current is passed through it.
Where is the pin on the solenoid valve?
The pin is located near the solenoid coil. When the solenoid coil is activated, the magnetic field draws the pin back, which pulls the stopper back and breaks the seal with the inlet pipe, allowing the diesel fuel to enter the solenoid valve.
What happens to fuel injector when engine is shut off?
Fuel injectors deliver fuel to the combustion chamber directly or indirectly. During its evolution; the fuel injector has moved from the intake manifold to the combustion chamber. Over time the nozzle of the injector can become dirty; and partially blocked. When you shut off your engine; the injector will soak up the heat of the engine.
Where is the fuel shutoff solenoid on a GM car?
“Circuit Description: When the ignition switch is in the “OFF” position, the Engine Shutoff Solenoid is in the “NO Fuel” position. By providing a ground path, the PCM energizes the engine shutoff solenoid which then allows fuel to pass into the injection pump.” Also found elsewhere in the GM service manual.
Can you bypass fuel shut off solenoid on injector?
So, you mean that, once you’ve pulled out the plunger, the fuel shut off solenoid can remain as is on the IP, even disconnected, and that should not create any issue? How do you shut off the engine then?
How does the fuel injection computer regulate the EGR valve?
The fuel injection computer is the one that regulates the opening and closing of the EGR valve thru’ the application and release of vacuum (through a vacuum solenoid). One side of the EGR vacuum solenoid (the one that has only one vacuum inlet port) connects to the vacuum port labeled with the letter J on the throttle body.
What is the other side of the EGR vacuum solenoid?
The other side of the EGR vacuum solenoid has 2 ports. One is a vent port (that vents vacuum to the atmosphere) when the engine is idling. The other port connects to the EGR valve and should only have vacuum when the PCM commands the solenoid to activate.
