The performance of your diesel injector system and your diesel engine as a whole lies on careful and regular maintenance. Much like every piece of machinery, your fuel injector system requires maintenance. To begin your maintenance procedure you may have to test your fuel injector. The results will determine if they need repairs or replacement. The good news is, you can do it yourself at home.
How to Test Your Diesel Fuel Injector
In today’s post, we give you steps you could follow to rest your diesel injectors under 30 minutes.
What You Need
- A screwdriver
- Automotive test light
- Eye goggles
- A metal rod – 1 ft in length
Step 1: Get the tools
You’ll first and foremost have to get the tools listed above where you’ll work. You don’t want to move around a lot. Best to have them within your reach.
Step 2: Listen for a Clicking Sound
With your diesel engine running, use either the screwdriver or the the metal rod to listen for clicking sounds. Place the screwdriver or metal rod on the fuel injector, listen in close for a clicking sound. The sound signifies that the fuel injector is in operation. Whatever the outcome, proceed to the next step.
Step 3: Turn on Your Electrical System
This step is very easy. Turn off your engine but leave the electrical system on. If the electric system is on, the head lights should come on along with other electronic features.
Step 4: Test Your Injector Connection
Locate an exposed bit of wire connected to your injector, attach the positive clip of your test light to the wire you’ve found and attach the negative clip of the light to the negative terminal of your battery. If the test light comes on, then the connection is in order. Do the same the other injectors.
Step 5: What Next
The outcome of the other steps determine what you’ll do next. If your injectors are not making the clicking sounds in the second steps but their electric connection is working, you may have to replace your injector.
One could contribute to the failure of diesel fuel injectors, such as the accumulation of deposits.
