There are a lot of parts that are exclusive to a diesel engine, and one of those would be the shutdown solenoid. Also known as the fuel shutoff solenoid, this can shaped device is responsible for managing the flow of fuel in a diesel engine. Once this particular component wears out, then your engine probably won't start, so you'd better have it replaced ASAP. This is a pretty standard part, and finding it online shouldn't be hard. Read through our short guide to make sure that you get all the right items when getting a shutdown solenoid for your ride.
How it works
The shutdown solenoid is actually a very simple device. When you turn it on, the plunger inside it will retract an allow fuel to pass through. Once you turn it off, the valve spring will push the poppet back down to cut off the flow of fuel. The shutdown solenoid can be manually activated, but most vehicles would have an automated engine management system that will handle it for you instead. The most common problem with a shutdown solenoid is a loose electrical connection. But once you rule that out, then you'll have to replace the entire device instead.
What to look for
We recommend that you get an OEM replacement that's made specifically for your vehicle. You'll also have an easier time installing a shutdown solenoid when you get a complete kit. Most of these kits should have all the necessary mounting brackets, screws, and electrical connectors. You could get a standalone shutdown solenoid on your own, but you have to make sure that it's compatible with the mount on your old shutdown solenoid and that you have the necessary bolts and screws to keep it in place. Unfortunately, the shutdown solenoid isn't an inexpensive part. Even a basic one could cost you about $100 to $250 at most.
