Diagnostics

Diesel fuel system diagnostics is the process of finding and fixing problems within the fuel system to keep your engine running at its best. Modern diesel engines rely on advanced common rail systems with electronically controlled injectors, which means even small issues like air leaks, clogged filters, or worn injectors can cause bigger problems such as hard starting, loss of power, excessive smoke, or poor fuel economy. Our diagnostic service carefully checks both the low-pressure and high-pressure sides of the fuel system using specialised tools and scan equipment. This allows us to monitor how your system is performing in real time and pinpoint any faults with components such as the lift pump, fuel filter, injectors, high-pressure pump, or sensors. By accurately identifying issues early, we can prevent costly damage, improve efficiency, and keep your engine running smoothly and reliably. At D&C Fuel Injection, our expert diagnostics give you peace of mind that your diesel fuel system is performing exactly as it should.
