How We Test Diesel Fuel Injectors

Last updated 5 years ago

A number of symptoms can indicate that your car has faulty fuel injectors that need to be repaired, including a gas leak, engine surging, or irregular idling. To find out how fuel injectors are tested at your local car repair shop, watch this video clip.

The technicians at an auto repair shop will use a machine to pump test fluid through the injectors. This machine will also measure the amount of pressure required to pump the test fluid through the nozzle of your vehicle’s fuel injectors. Technicians will be able to tell if something is wrong with the fuel injectors if they notice a distinct spray pattern and an irregular amount of pressure required to send fluid from the injector nozzle. Check out the video clip for more information about how fuel injectors are tested by car repair professionals.

To have your fuel injectors tested by the car repair experts at A-1 Auto Tech, Inc., visit our repair shop in Mountain View, CA. If you have any questions about your fuel injectors, call us today at (888) 722-1970.
