Diesel Pump & Injector Repair
Common Rail & Mechanical Fuel Injection Specialists.
Millennium Power (MPOM) provides specialized diesel pump and injector repair for every type of diesel-powered vehicle and machine — from passenger cars and pickup trucks to commercial fleets, heavy equipment, and marine engines. Using dedicated mechanical and Common Rail test benches, our technicians test, repair, and calibrate diesel fuel pumps and injectors to restore precise fuel delivery, smoother starting, and full engine power.
Every pump and injector that enters our workshop is diagnosed on the bench before it is repaired. Injection pressure, flow rate, and spray pattern are measured against manufacturer specification to pinpoint wear, clogging, or calibration drift — the root causes behind hard starting, white or black smoke, rough idling, power loss, and rising fuel consumption. Once the fault is confirmed, nozzles, seals, valves, and internal components are replaced with quality-matched parts, and the unit is recalibrated and re-tested under load before it goes back into service.
This diagnosis-first approach is why fleet operators, contractors, and diesel vehicle owners across the Eastern Province trust MPOM with fuel injection problems other workshops can only guess at.

Diesel Fuel Injection Repair for Every Type of Diesel Engine
Diesel pump & injector faults show up differently depending on what the engine is powering, but the underlying fuel injection system works the same way across applications. Our test bench capability covers diesel fuel injection repair for:
Cars & SUVs
Diesel passenger vehicles losing power, smoking, or hard to start
Pickup Trucks
Light diesel workhorses that need reliable cold starts and full towing power
Commercial Trucks
High-mileage fleet vehicles where injector wear directly impacts fuel cost per kilometer
Buses
Passenger and staff transport fleets that cannot afford unscheduled downtime
Heavy Equipment & Construction Machinery
Excavators, loaders, & cranes running under continuous high-load cycles
Agricultural & Industrial Equipment
Diesel-driven machinery where injector precision affects fuel economy across long operating hours
Marine & Boat Engines
Diesel injection systems exposed to demanding, corrosive operating conditions
Diesel Generators
Pump & injector repair specifically for the fuel injection system, supporting stable power output and clean combustion
Whatever the application, the diagnostic &repair standard does not change: measure, diagnose, repair with correct parts, & recalibrate to specification before the unit is returned to service.
Our Diesel Pump & Injector Services
We provide complete, bench-tested diesel fuel injection repair, including:
Full fuel injection system check to identify the source of performance faults before any part is opened.
Removal of contamination and carbon buildup that restricts fuel flow and reduces injection accuracy.
Mechanical and Common Rail pump servicing, rebuilt and recalibrated to manufacturer flow and pressure specifications.
Bench testing of spray pattern, opening pressure, and flow rate to confirm injector condition against tolerance.
Ultrasonic cleaning, nozzle and seal replacement, and functional re-testing to restore correct atomization.
Diagnosis and repair of electronically controlled Common Rail injectors and high-pressure pumps, including coding and calibration to injector-specific values.
Rebuild and recalibration of mechanical (inline and rotary) diesel injection pumps for older and heavy-duty engine platforms.

Our Diesel Testing & Calibration Equipment
Diesel fuel injection repair is only as accurate as the equipment used to verify it. Guesswork and visual inspection are not enough to confirm a pump or injector meets specification — that requires bench testing under controlled pressure and load. Our workshop is built around dedicated test benches for both major diesel injection technologies:
Mechanical Test Bench
Used to test & calibrate mechanical inline & rotary injection pumps found in older & heavy-duty diesel engines - trucks, buses, heavy equipment, agricultural machinery, & marine engines. The bench verifies delivery volume, timing, & injection pressure at multiple RPM points, so a rebuilt mechanical pump is proven to specification before it leaves the workshop.
Common Rail Bench Test
Used to test & calibrate modern electronically controlled Common Rail injectors & high-pressure pumps. The bench simulates real operating pressure & measures return flow, injection quantity, & spray pattern for each individual injector, catching faults that a visual check or road test alone would miss.
Testing every pump and injector on the correct bench — before and after repair — is what allows us to guarantee the work: what goes back into your engine has been measured, not assumed.

Our Expert Technicians
Our diesel fuel injection technicians are trained specifically on Common Rail & mechanical pump and injector systems – a discipline distinct from general engine repair. Each technician works to the same standard regardless of what the engine is powering: bench-diagnose the fault, confirm it against manufacturer specification, repair with correct parts, & re-test before handover.
This specialization matters because diesel injection faults are easy to misdiagnose without the right equipment – a worn injector, a failing pump, & a compression issue can all present as the same symptom of power loss or excess smoke. Our technicians separate fuel system faults from other engine issues using bench data, not assumptions, so the repair addresses the actual cause the first time.
From a single vehicle’s injector to a fleet-wide pump servicing program, the working standard is the same: test, verify, repair, retest.

How Our Diesel Injection Repair Process Works
Frequently Asked Questions
Diesel pump and injector repair restores the fuel injection system's ability to deliver fuel at the correct pressure, timing, and spray pattern. Common signs you need it include hard or extended starting, black or white exhaust smoke, rough idling, noticeable power loss, knocking noise, or a sudden drop in fuel economy. Bench testing confirms whether the pump, the injectors, or both are the cause.
Yes. We run separate test benches for each: a Common Rail bench for electronically controlled high-pressure systems used in most modern diesel engines, and a mechanical test bench for inline and rotary pumps found in older and heavy-duty platforms. Each system is tested and calibrated on the correct bench for its technology.
We repair diesel pumps and injectors for cars and SUVs, pickup trucks, commercial trucks, buses, heavy equipment and construction machinery, agricultural and industrial equipment, and marine and boat engines. We also service the fuel injection system on diesel generators specifically — our focus stays on the pump and injector, not general generator maintenance.
Every unit is mounted on the appropriate test bench and measured for injection pressure, delivery volume, timing, and spray pattern against manufacturer tolerance. This happens before repair, to confirm the fault, and again after repair, to verify the rebuilt unit meets specification before it is returned to service.
Turnaround depends on the fault and parts availability — a single injector cleaning and re-test can often be completed within a day, while a full mechanical pump rebuild or a multi-injector Common Rail job may take longer. We confirm a committed timeline once the bench diagnosis is complete and the quotation is approved.
Yes — where the fault is in the generator's diesel pump or injectors, we test and repair that fuel injection system using the same bench equipment used for vehicles and heavy equipment. This service is limited to the pump and injector system, not general generator maintenance.
Our test benches and technicians support major diesel injection brands including CAT, Cummins, Delphi, Denso, and Bosch, across both Common Rail and mechanical pump systems.
Cost depends on the diagnosed fault, the injection technology, and the number of components affected. Every job starts with a bench diagnosis and is followed by a clear, itemized quotation before any repair work begins — so you know the exact scope and cost in advance.
