Parts for your 2000 Daihatsu Gran move-Fuel injectors

2000 Daihatsu Gran Move fuel injectors – what they do and how to look after them

Based on technical literature for the Daihatsu Gran Move (G303/G311, also sold as the Pyzar), this model uses electronically controlled multi‑point fuel injection, so fuel injectors are absolutely fitted and relevant. The Daihatsu G303/G311 workshop manual’s Engine Control System section outlines an EFI system with individual cylinder injectors, and the Daihatsu/Toyota electronic parts catalogue lists the injector assemblies and associated O‑rings/seals for the 1.5–1.6 litre HC‑/HD‑series engines used around 2000. Period market brochures for AU/NZ also specify “EFI” rather than a carburettor setup.

On the 2000 Gran Move, the injectors’ job is to deliver precisely metered, finely atomised fuel to each cylinder at the right time. That accuracy helps cold starts, smooth idle, decent torque for city running, better fuel economy, and lower emissions. With multi‑point injection, each port gets the right amount of fuel under ECU control, using inputs from sensors like the oxygen sensor, throttle position sensor, and coolant temp sensor.

As for servicing, injectors aren’t a routine replacement item, but they do benefit from periodic attention. Good practice for Aussie and Kiwi conditions is:

• Use quality unleaded fuel (E10 is generally acceptable for late‑’90s Daihatsu EFI
