Diesel Injector Testing
Every injector measured against manufacturer data before any work is quoted.
- Spray pattern & back leak
- Delivery across the range
- Printed test report
Tested. Repaired. Coded.
Diesel & Petrol
Fuel Injection
Measured, not guessed.
Injectors and pumps are diagnosed on the bench against manufacturer data, repaired to specification and coded back to the vehicle — so the fault is fixed rather than swapped around.

Diesel Injector Repairs & Reconditioning
Stripped, rebuilt with genuine components and retested before it goes back on the vehicle.
- Genuine components
- Flow matched sets
- 6 month warranty
Common Rail Pump Testing
Rail pressure and delivery checked properly, so a weak pump is not misread as a bad injector.
- Pressure & delivery
- Bosch, Denso & Delphi

Diesel Pump Repairs
Injection pumps rebuilt to specification and calibrated on the bench.
- Full strip & rebuild
- Calibrated to spec
- 6 month warranty
EUI & EUP Injector & Pump Repairs
Unit injectors and unit pumps for heavy duty equipment — stripped, rebuilt and calibrated on the bench.
- Trucks, tractors & plant
- Rebuilt & calibrated to spec
- 6 month warranty
Injector Coding
Correction codes written to the ECU so the engine runs smoothly on the injectors it actually has.
- IMA / IQA coding
- After fitment or replacement
- Smooth idle & running
Diesel Pump Testing
Mechanical in-line and rotary injection pumps run up on the bench and measured against the calibration data.
- In-line & rotary pumps
- Delivery & timing checked
- Tested before it is stripped
Six Month Warranty
Every reconditioned injector and pump leaves here with a six month warranty. It is tested before it is fitted, and tested again afterwards.

Common Questions
How do I know whether my injectors are the problem?
We test before we quote. Each injector is measured against the manufacturer data for spray pattern, back leak and delivery across the range, and you get a printed test report. We also test the high-pressure pump, because a weak pump reads like bad injectors and swapping injectors will not fix it.
What warranty do you give on reconditioned injectors and pumps?
Every reconditioned injector and pump leaves the workshop with a six month warranty. It is tested on the bench before it is fitted and tested again afterwards.
Do you code injectors to the vehicle?
Yes. We write the IMA and IQA correction codes to the ECU after fitment or replacement, so the engine runs on the injectors it actually has. Skipping this step is why a set of good injectors can still idle roughly.
Which injection systems do you work on?
Common rail injectors and pumps from Bosch, Denso and Delphi; mechanical in-line and rotary injection pumps; and EUI and EUP unit injectors and unit pumps for heavy duty equipment — trucks, tractors and plant.
Can you repair my injectors or do they have to be replaced?
Most can be repaired. Injectors are stripped, rebuilt with genuine components, flow matched as a set and retested before they go back on the vehicle. The test results tell us which ones are worth rebuilding, and that is the conversation we have before you spend anything.
What are the symptoms of a failing diesel injector or pump?
Hard starting, white or black smoke, a rough idle or misfire, poor fuel economy, a loss of power, or a rail pressure fault code. Any of those is worth testing rather than guessing at — bring it in and we will measure it before we quote.
