Holden Rodeo 2005 Problems

HOLDEN offered a dual-fuel system for the RA Rodeo with the 3.5-litre V6 engine and that's the one I would recommend. It was developed by Impco and sold through Holden dealers. The warranty will be affected by modifications made to install the system. That means Holden won't cover the engine and other parts of the car that have been modified. You need to talk to the person installing the system to see what cover they provide for the equipment they supply and the work they do.

This is very possibly a fault with the power supply to the fuel pump rather than the pump itself. The clue is that the fuel gauge started playing games just before the engine shut down. The fuel gauge is controlled by the sender which is usually in the tank with the pump. They’re often supplied power by the same wiring. So any problem with the power to the fuel pump would also possibly show up as a fuel gauge that’s making strange movements.

Start by checking the power supply to the pump, but don’t rule out a poor earth somewhere in there as well. Even though the fuse is okay, if the power wire or earth wire is loose/corroded/faulty/dirty/short-circuiting, then you may have found the problem.

The 3.5-litre Rodeo uses more fuel. I recommend the Toyota. Consider a diesel if you are concerned about fuel economy.

Let’s start with the basics here. Is your vehicle a petrol- or diesel-engined Rodeo? If it’s the former, you may have disturbed the wiring when changing the filter. So go back and check all the connections. If you can’t hear the pump whirring when you turn on the ignition, then you either have a fuse or wiring problem or the pump itself has died.

It’s pretty common for this to happen and most electric fuel pumps have a lifespan of something like 100,000km. But this can be a lot shorter if the car has ever been filled with contaminated fuel.

If your Rodeo is a diesel, there’s a chance it will need to be primed before it will restart after a filter change. That is, it needs to have any air in the fuel system removed before it will run. Locate the fuel filter in the engine bay, and you should see a small plunger at the top. With everything refitted, you can manually push on this plunger to prime the pump and remove any air. All things being equal, the engine should then start and run.

Speaking of back to basics, make sure you haven’t installed the new fuel filter the wrong way around. These only flow in one direction and installing it backwards will not allow the fuel to flow from the tank to the engine.

Yes it did. In order to produce the engine’s 96kW and 280Nm of torque (291Nm in automatic form), Holden - or rather Isuzu, who engineered the vehicle and provided the driveline - used an intercooler to achieve that level of performance.

The factory intercooler was a top-mount (mounted on top of the engine) and there are plenty of aftermarket alternatives when it comes time for replacement. Some owners also choose to fit a front-mounted intercooler for better performance, although in an off-roader like the Rodeo, this can place the intercooler in harm’s way in an off-road scenario.

AFTER thoroughly checking LPG kits and fitters, Holden has approved an LPG kit and certified fitters to install LPG in the Rodeo. If you get this kit and it's fitted by one of the approved fitters, your warranty will not be affected. Check with your dealer and ask him to show you that the kit and fitting company he is using are approved by Holden. He will have the information on hand.
