DIAGNOSE. REPAIR. REBUILD. RESTORE. CALIBRATE.
Diesel fuel injection testing, repair, rebuilding and calibration for component owners, independent shops, farms and fleets nationwide. Submit your pump or injector part number for a mail-in service review before shipping. At DCT, you’re never just a number.
Start with the part number, the symptoms and a quick conversation with DCT. We review the component, confirm whether it is a fit for our process, and send clear receiving and shipping instructions so you can move forward with confidence. Do not ship before written approval.
Tell us what you have, what it came off of and what it is doing. DCT reviews eligibility and gives you the right next step before your component ever leaves your hands.
Once the component arrives through the approved intake process, DCT evaluates it, explains what the findings really mean and outlines the service options that make the most sense.
After you approve the work, DCT completes the authorized service, performs the appropriate verification and helps get your component on its way back to the job.
NATIONWIDE MAIL-IN / DCT SPECIALIST SERVICES
Every pump and injector story starts with the same goal: get the right answer before time and money are wasted. DCT combines technical evaluation with practical guidance, so customers across the country can move from uncertainty to a clear service plan.
INJECTOR PERFORMANCE
When an injector is smoking, misfiring, leaking or simply suspected, the right next step is not guesswork—it is a disciplined review of the injector type, the symptoms and the supported bench procedures. DCT helps determine whether your unit is a candidate for testing, cleaning, rebuilding or calibration.
PUMP DIAGNOSIS
A hard-start, low-power or fuel-delivery complaint does not automatically point to one failed part. DCT begins with identification and evaluation, then explains what the component can reveal, what it cannot, and whether repair or rebuild deserves the next conversation.
COMPLETE RESTORATION
Some units need more than a seal, a cleaning or a quick adjustment. When the evidence points toward a more comprehensive solution, DCT can discuss approved repair and rebuilding paths built around the exact assembly, available parts and the verification required to stand behind the work.
FINAL CONFIDENCE
The real value of specialist service is confidence on the back end. Supported calibration and verification procedures help confirm that the finished component meets the approved scope and is ready for the next stage of installation, startup and service.
A SPECIALIST MINDSET
An injection problem can stop a truck, delay a harvest, or take a critical machine out of service. It deserves more than trial-and-error parts replacement.
Our approach begins with identification, the reported failure, and a component-specific evaluation. We explain what can be tested, what can be restored, and when replacement deserves consideration—so you can decide with the right information.

THE WORK WE’RE KNOWN FOR
These six service stages show how DCT thinks: identify the component, understand the evidence, choose the right remedy and verify the result. Not every job needs all six stages, but every great outcome benefits from this kind of discipline.
Every successful repair starts with clarity. DCT looks at the exact component, the application and the complaint so the next recommendation is based on evidence rather than assumption.
Different injector families require different questions and different test methods. DCT helps determine what can be measured, what the results mean and what the smart next move should be.
Contamination and deposits can sometimes be corrected—but only when the component is still a good candidate. DCT separates true restoration opportunities from situations that call for a bigger solution.
When the problem is specific and the repair is technically appropriate, DCT focuses on the defect itself so the customer gets a targeted, purposeful recommendation instead of unnecessary work.
For pumps and injectors that deserve a deeper restoration path, DCT can discuss a controlled rebuild or overhaul process grounded in approved parts, inspection standards and serviceable component condition.
Specialist work is only complete when the finished component is checked against the supported procedure. Calibration and verification help turn a repaired component into a confident return-to-service decision.
PUMPS / INJECTORS / FUEL SUPPLY
A century-old mechanical pump and a modern common-rail injector may share the same diesel engine vocabulary, but they do not share one test or repair method. The story changes with the technology.
01 / MECHANICAL PRECISION
Inline and rotary injection pumps use precise mechanical relationships to control fuel delivery. Governors, advance mechanisms and pump identification all influence the right service conversation.Discover mechanical injection pumps
02 / ELECTRONIC CONTROL
Electronic distributor pumps and controlled injection systems add actuators, sensors and wiring to the equation. The symptom may look familiar while the diagnostics are completely different.Explore electronically controlled pumps
03 / MODERN PRESSURE
Precision fuel pressure and rapid injector control can expose issues with supply, contamination and component wear. Correct identification is the starting point for meaningful testing.Understand common-rail injectors

FUEL-INJECTION MAKERS & APPLICATIONS
DCT reviews inquiries involving a wide range of diesel pump and injector manufacturers, plus engine and equipment applications. The exact part number determines what service is possible.
PARTS IDENTIFICATION & SOURCING
From light-duty pickups to commercial trucks and heavy equipment, the correct turbocharger begins with an exact part number and engine application. Ask our team about eligible new, remanufactured and exchange options, availability and fitment verification.
Turbocharger sourcing and replacement inquiries are separate from DCT’s specialist fuel-injection testing and rebuilding services. Repair, authorization and availability depend on the specific unit.
