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?
What causes a diesel injector to stop the engine?
If the injector is sticking due to wear then it can make a very loud knocking noise which may come and go at random. Common rail injector failure is usually sudden and will stop the engine for no apparent reason. The solenoid in the injector being the weakest part is usually the culprit, and can allow fuel to enter the cylinder unregulated.
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.
What kind of solenoid does an injector use?
Later types called Electronic Unit Injectors use a built in electrical solenoid to control the opening times of the nozzle.
How does a diesel fuel shut off solenoid work?
Diesel fuel shut-off solenoids transport diesel fuel from a machine’s gas tank to its engine. A diesel fuel shut-off solenoid is attached to the machine’s main electrical system, which can monitor and detect abnormal temperatures or mechanical malfunctions.
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 do you fix a faulty fuel solenoid?
As for cars or trucks with diesel engines, just stop at any service station and have them block the air intake and replace the faulty fuel solenoid. It’s not very expensive depending on the make or model of what ever you’re driving.
What happens if the solenoid does not open?
I.e., the solenoid doesn’t open, therefore you cannot get any fuel into the engine and it will not run. Fail open. I.e., the solenoid will not close and therefore will not shut off the fuel. The engine, if running, will keep running.
