Diesel and Gas Fuel Injector Testing in NH

Is your engine having difficulty starting or firing? Your fuel injectors could be experiencing a number of issues. Our skilled technicians at Diesel’s Fuel Injection Service can test and diagnose your injectors and identify the problem, at an affordable rate.

We’re pleased to offer our customers the option of testing each injector individually. This means that, if there’s an issue, you can replace the individual injector, for much less than an expensive replacement of the entire set!

We use the state-of-the-art Hartridge CRI-PC machine which provides full-function testing capabilities, including a shot-to-shot analysis. We provide flush, flow testing, and resealing for multiple engine types and applications.
