Parts for your 2017 Holden Commodore-Fuel pump

2017 Holden Commodore fuel pump — what it does and how to look after it

Based on technical sources including the Holden VF Series II Service Manual (Fuel System Description and Operation), GM Global Service Information for VF Commodore, and AC Delco/Bosch parts catalogues for 2013–2017 VF models, the 2017 Holden Commodore absolutely uses a fuel pump. Every petrol variant is fitted with an electric, in-tank fuel pump module to supply pressurised fuel. On the 3.6L SIDI V6, there’s also a cam-driven high-pressure fuel pump on the engine that boosts pressure for direct injection. The 6.2L LS3 V8 uses the in-tank electric pump for its port-injection system.

On a 2017 Commodore, the fuel pump’s job is to move petrol from the tank to the engine at the correct pressure and volume. The in-tank module primes on key-on, runs quietly while driving, and includes the level sender and an internal filter/regulator. On SIDI V6 models, the in-tank pump feeds a high-pressure pump that delivers the extreme pressures required for direct injection. If the pump can’t keep up, drivers may notice long cranking, hesitation, loss of power under load, or fault codes like fuel pressure too low.

There’s no scheduled replacement interval for the fuel pump on a VF Commodore, it’s a “replace on condition” item. Sensible servicing includes scan checks for fuel-pressure related DTCs, listening for excessive whining from the tank, and verifying fuel trims under load. Keeping the tank above a quarter and avoiding consistently running on empty helps the pump stay cool and happy. Most VF petrol models use a non-serviceable, in-tank filter within the module, so there’s no separate filter change during routine servicing.

When replacement is needed, a technician will safely relieve system pressure, disconnect the battery, drop the tank (or access via the service panel where applicable), and swap the complete pump module. Fresh seals/O-rings and, where required, a new locking ring are a must to prevent vapour leaks. After installation, the system is primed and checked for leaks and correct pressure. For SIDI V6 cars, it’s also wise to assess the engine-mounted high-pressure pump and lines if low-pressure supply issues have been present. A light “tick” from the SIDI high-pressure pump can be normal, persistent hard starts, misfires on cold start, or fuel odour warrant further checks.

• Common symptoms: hard starting, surging, noisy pump, power loss on hills/overtake, lean or misfire codes.
• Good habits: quality petrol, keep some fuel in the tank, and address clogged filters or restrictions promptly.

Does the 2017 Holden Commodore have more than one fuel pump?

Yes for SIDI V6 models: there’s an electric in-tank pump and a mechanical high-pressure pump on the engine for the direct-injection rail. LS3 V8 models use a single electric in-tank pump for the port-injection system.

How long does a Commodore fuel pump typically last?

Many in-tank electric pumps go 150,000–250,000 km or more, depending on fuel quality, operating temperature, and usage. There’s no fixed replacement interval, it’s replaced when noisy, weak, or when diagnostics show low supply pressure.

Is the fuel filter serviceable separately on a VF?

On most VF petrol variants, the primary filter and pressure regulator are integrated into the in-tank pump module and aren’t a routine service item. If the filter is restricted, the remedy is typically a complete module replacement.
