    2003 VY Commodore Supercharger
    I have 2003 VY supercharge i turn the key it goes to start but won't kick over, battery light is on and the dash says check alternator, yes I know how to change it but can I replace it with a normal alternator or does it have to be supercharged? Also where is the starter motor located? Could that be the problem? I don't want to get underneath without sort of having an idea where to look my dad lives a long way away and he hasn't dealt with supercharged engines so I'm working alone

    Sounds like a flat battery.

    Your problem is most likely a flat battery. Try jump starting the car with help from another car (connecting your battery to the other cars battery). Get help from someone to make sure the connections are correct - positive to positive on batteries, negative to earth on your car.

    The alternator is not supercharged, only the engine is.

    The starter motor is located below the engine but don't concern yourself with it until you have eliminated the battery as the cause of your problem.

    This might be worthwhile for you https://rac.com.au/car-motoring/roadside-assistance
    Between $2 and $4 a week depending on which level of service you choose, it is good value.
    They will come out and tell you what is wrong, and get it going if they can.
    As already mentioned, don't go playing with the starter until you are absolutely certain of the battery.
    How old is the battery and have you cleaned the terminals on the battery.
    The starter is usually accessed down low on passenger side of the engine at the rear of the engine.
    May have an aluminium cover over it but don't try anything with it without first disconnecting the battery.

    If it starts now.......But you did NOT say that in your original post......How long does it run for? If only a short time then sounds like lack of fuel???

    The most simplest thing ive never even thought of, it is a little bit low so I will try putting more fuel in it and see how it goes

    You should NEVER let your tank get below 1/2, particularly on old cars as they will pick up the crud in the tank from from so many years and fill ups.
    This will block the filter, and this could well be your problem as well. You will see the filter near the tank, but be VERY careful if you decide to change it as will probably have fuel running everywhere.
    As a matter of interest are you running it on premium fuel?......If not best you do may I suggest.

    Ease up turbo, your gonna scare the poor girl out of cars completely! I have 93 vq statesman and ive run that low on fuel plenty of times. The difference between 98 octane and PULP (91 or lower) is so insignificant to a daily driven road car its silly. In the united states they often run 80-87 octane and theyre cars have no hassles running on it. In fact i have seen huge horsepower cars run on it. A decent fuel additive for cleaning purposes run through your tank once a month will have rectified fuel being grubby or dirty. Replacing a fuel filtwr and cleaning the injectors will solve a lot of that. Let thw forum know how you got on mate.

    Another problem with that model commodore is if the car is on a slight incline to the kerb, the pump will often not pick up fuel if the tank is under quarter full.

    I stand by my statement, DON"T allow your tank to get low, as it WILL pick up crud and perhaps block the filter. Particularly on older vehicles.

    Re. numbers on petrol you are talking, are you aware Australia and USA run different numbers for octane value? I have lived in the USA by the way.

    I agree with the additive to clean things out.......Toyota make a very good one. First thing here though is to help this girl and at least get the car running, if we can.

    The supercharged VY is meant to be run on premium fuel, and 95 would be fine. It will run of course on 91 as it has a knock sensor, but 95 is best for it, and 98 not needed.

    Not below half tank and not getting too low are two very different things.

    Going too low should definitely be avoided as you can end up overheating the fuel pump leading to its untimely death.

    Not going below half tank is overkill imho.

    Yes - what Gossie said.
    - Your fuel pump also needs plenty of fuel for cooling and for lubrication. You don't want to run extremely low on fuel and risk have the pump running dry gasping to pick up the remaining fuel sloshing around in the bottom of the tank as you are driving up some incline.

    - Had 2 of the V6 supercharged engines. Great engines for their time and you definitely should run them on 95 octane fuel.

    Ahhh i had completely forgotten the RON data details re: usa/aus! My apologies. I often let my statesman run as low as a quater tank but never less than that. Now you have me worried haha.

    1/4 tank is fine by me, but if you drum 1/2 tank into people maybe, just maybe they will at least start to think about filling their tank when it gets to 1/2 way down.

    We have not heard back from this girl????? Perhaps she got it going?????

    Actually thats a smart way of thinking. My girlfriend drives a series 3 vs 5 litre ute and thats the approach i have had with her refilling fuel. I had forgotten this altogether.

    Anyway, back on topic....when you turn the key to the ON position, does the red immobilisor light turn off?
