i Can here the fuel pump when I try to start it stereo work dashlight work everything electrical works fuses are ok so dont think its the battery or alternator only noise it makes its the fuel pump when try to turn it over.


I was thinking starter motor was stuffed but I dunno.

Sounds like a CAS problem.

If its not even cranking over then I am pretty sure the problem will be before the CAS. If the battery is good and has plenty of charge then I would be looking into the starter motor and the wiring that runs to it.

It could also be the neutral safety switch, maybe with the handbrake on try to see if it will crank when it is in N or P.

also read on another forum i could need a new key? Anyway how do you change the cas ?

[James39]

I woulld be looking at the keyhead... Are you able to lock and unlock the car with the remote?

yeah it unlocks but have to keep pressing the button tell it unlocks half the time just and up using the key to unlock the door

Does the immobiliser light go off when you turn ignition on?
If not, it's probably the key not making proper contact with the key reader -

I have what looks like 2 immobiliser lights one under the cd/mp3 player and one under the light switch

Wouldn't even look into the CAS until you get it cranking. Like mentioned above I would be looking into the starter motor and solenoid first, try and get underneath or from up the top with a hammer or long metal pole and give it a few good wacks while someone tries to turn the key.

check your battery terminal connections

Do they go off when you try to start it? If no then it is the keyhead at fault. either get a new key programed or replace the battery within....

It turns off when the key is in :/ only Way I can start it is by shorting out the starter Motor

[m62vpute]

If you can get it to run by shorting out the starter motor then the problem will be that the starter is not getting the voltage to the trigger (on the solenoid) to tell the starter motor to crank.

Check for any blown fuses as well as having a look at the relay that is under the bonnet START and EFI you can swap them with your headlight relay to see if it works

Just tried it no luck Anyone know a auto electrician in WA lol

[Aussie Revhead]

anyone have any other ideas

[Aussie Revhead]

might have figured out the problem ignition switch is what a family mechanic told me anyway how do you tell if it is stuffed cheers.

[Jxw]

probe the back of the ignition switch/plug/wires with a multimeter, see if you are getting power to the start trigger wire/terminal

[Aussie Revhead]

put a new ignition switch in it still wont start :/

[Jxw]

in front of the relay/fuse box in the engine bay, find the thick purple/violet wire and undo the plug (2 wires in the plug purple is start signal to solenoid, other is dash light for altenator form memory ignore that one)

test this for voltage when ign switch to the start position, if you're getting power to that then the problem is between that plug and the starter motor solenoid.....
if there's no power can you hear the start relay clicking?
