Diesel injector pump repair cost in Australia

Updated 5 November 2026

On this page: prices

A diesel injector pump repair in Australia depends on the part: a high-pressure pump for a common ute starts around A$1,700 before labour, and a complete fuel pump replacement by a mechanic costs A$400 to A$1,200. Single injectors are A$240 to A$445 each, according to sellers' websites and cost guides in October 2026. The quickest way to a figure for your own car is a free request on BlaBlaPrice.

Licences and training to check

Diesel fuel work is trade work. The national unit AURTTF3004 Repair diesel fuel injection systems sets out the skills needed, and a Certificate III in Automotive Diesel Engine Technology is one of the qualifications that trains people for it. In South Australia, diesel fuel system tradies are required to hold the appropriate licences, so ask any workshop to show its licence and insurance before you book.

Season and climate

Australia's seasons run the reverse of the northern hemisphere. November is spring, summer runs from December to February and winter from June to August. A check before winter gives you time to fix a fault before the cold months, and before the long summer trips from December to February.

How quotes and labour are charged

Quotes are in Australian dollars. One supplier shows its parts prices including GST, so ask whether a quote includes GST and labour. Labour is charged per hour, and a mobile diesel mechanic adds a call-out fee of A$60 to A$150, which suits a ute parked at home in Sydney, Melbourne, Brisbane, Perth or Adelaide. Give the workshop your suburb, since a mobile visit depends on the distance from the mechanic to your car.

What to write in your request

Include the make, model and engine, the fuel system part you think is faulty and the symptoms, such as hard starting or lost power. Say how many injectors or pumps are needed, whether the part is still on the car or already removed, your city or area, your deadline and your budget.

On BlaBlaPrice you describe the fault in your own words in a free chat, and you can add a photo. The AI asks for missing details, looks through sellers' websites and price lists in Australia, then shows the prices and businesses it found. Registered sellers reply in the chat with their price, terms and delivery, and your contact details stay hidden until you decide to exchange them. You can also send the request link to a workshop you already know. For related work see Engine repair or Car computer diagnostics.
