About EIS Diesel

Our EIS Diesel Family

Electronic Injection Services is a family-owned diesel performance and repair shop. We started business back in 2000 and have turned into one of the most trusted light duty diesel shops in the Northwest!

Whether you use your diesel vehicle for work or fun, we can provide you with on-site testing, diagnostics and repair for straight forward answers about your diesel vehicle’s performance. With over 50 years of experience in the mechanical and electronic diesels, our continual training provides us with the knowledge and experience to keep us at the front of the changing diesel market.

With the growing number of diesel vehicles, the aftermarket repair shops have fallen behind in keeping up with the new technology. Being a trusted business within the diesel community has given us an opportunity to receive training on the newest of vehicles and in some cases make warranty repairs. EIS prides itself in being able to not only diagnose your problems but test components with state of the art test equipment and repair them in house. Our goal is to provide the best product and services to our customers at a reasonable price.

Jon Kari

Owner / Founder

I started the business back in 2000 with over 20 years of previous diesel experience. It was an opportunity to bring my vision and specialties to my own shop. With my love for diesel vehicles and drive to create a trustworthy relationship with clients, we started by testing and rebuilding diesel injectors, which quickly transformed into what the business is today.
