As the Sunshine Coast’s diesel fuel injection specialists, we offer a full range of services, from diesel injector testing and coding, to engine diagnostics.
With a well equipped workshop, factory-trained technicians, and years of experience, there’s no job we can’t handle.
Regular maintenance of your diesel fuel injection system is essential for peak performance and optimum results. It will keep your system working better, for longer.

Diesel Injectors

The servicing and repair of diesel fuel injection equipment requires specialist knowledge and equipment. Your vehicle’s diesel injectors must deliver the right amount of fuel, at the precise moment that it is needed to ignite your engine.
Common Rail Injectors operate at very high pressures, and must be properly tested and calibrated. Signs that your diesel fuel injectors may need servicing or repair, include power loss, increased fuel usage, and/or black smoke.
North Coast Diesel Service measures the performance of your Common Rail Injectors on our Maktest injector tester. This specialist piece of equipment goes through 7 tests automatically, to check every function of the injector. We are then able to print out the results, and give the injectors the thumbs up – or down.

We offer;

  • Removing and refitting of injectors
  • Coding of Common Rail Injectors in engine
  • Only GENUINE parts used in repairing injectors
  • A firm price before work begins

Diesel Injector Pumps

The heart of your diesel fuel injection system is the pump. And if that pump isn’t beating correctly, you could be in trouble!
Signs that your diesel injector pump may need attention include low fuel pressure, a high pitched sound, acceleration problems, and loss of power.
North Coast Diesel Service can maintain, service, diagnose and repair diesel injector pumps at our centrally-based workshop.
We also service exchange units for a large range of 4WD vehicles.

  • 12 months or 20,000km warranty on repaired units
  • All genuine parts
  • Advice on the removal and refitting of pumps
  • Upgraded injector pumps rebuilt to fit Toyota 1HZ ,Nissan TD42 and Nissan TD42T for better performance

Electronic Diagnosis

Our fully equipped workshop includes a range of diagnostic scanning tools, including Bosch, Carmen, Launch, and G-Scan. Scanning is an essential part of electronic diagnosis and our experienced technicians are fully trained to carry out this service.
Using this equipment, we can read fault codes, input the codes for new injectors, and perform special functions to isolate the fault.
If your vehicle is not running as well as it should, we will use our diagnostic tools to find the source of the problem. We can then professionally repair your diesel injection system, or advice you accordingly.

Common Rail Systems

What Is An CRDi Engine? CRDi stands for Common Rail Direct injection. This means the direct injection of fuel into the cylinders of a diesel engine via a single, common line – the common rail – which is connected to all the fuel injectors. The more sophisticated technology becomes, the more potential downsides there are.
Common Rail systems are usually more expensive to repair and there is more to go wrong. This can include cam and crankshaft sensors, air mass meter, pressure and relief valves, solenoids, EGRs, DPFs, and map sensors.
Repairs can be kept to a minimum by regular servicing, and fitting a pre or secondary fuel filter. The Fuel Manager kit comes with a bracket, hoses, filters, and all fittings. See our Products section.

Dos And Don’ts For Diesel Fuel Injection Systems

  • If you remove injectors, DON’T clean the nozzle with a brush or buff them
  • DON’T wash the engine bay with a high pressure water hose
  • If you are getting a smell of exhaust gases, compression may be leaking past the injector seal in the head. We have a 10 ton ram to remove injectors seized in the head by carbon blowby. DON’T try and do this yourself.
  • DO fit a new filter every 10,000km – no matter what the service schedule says.
