Car Behaving Badly

[Dinwoodie]

Hey everyone,
Ok, lately ive been having some problems with my VS, first it was cutting out when i was driving up and not starting for a while, so i replaced my ignition module, after i installed it the car didnt want to start at all it was just turning over but not starting, i did an error code check and it come up with code 12, everything was fine, so i went to start the car agian and it started first go. (this was about 2 weeks ago)

The other day i was out doing some shopping and when i returned to the car i tryed to start it and had the same problem it was just kicking over and no start, i kept trying for a while to start it with no luck, So once again i did a check for error codes and got error 12 again. so i turned the car over agian after getting the code 12 and it started first go. Does anyone know what might be wrong with my possessed beast?

did you check the dfi board was installed right? You might have got a dodgy new board to

Cutting out while driving is usually an indication of a faulty crank angle sensor.

+1 for CAS
dude, carry a bottle of water with you in the car, on those days you can't get it to kick over pour water over it and let it cool...
Then replace it... CAS won't always throw an error if working intermittantly...

Yeah,Id say it could be the crank angle sensor,its a fairly common problem when they get old.The harmonic balancer needs to come off to replace it.You will need a harmonic balancer removal tool(puller) if you are going to do it yourself.They aren't very expensive.

wicked now i know where else to look!

Is there any reason it wont work up untill a put the car into test mode? and then fire up straight away?

When i got the change over ignition module the bloke that fixes them rang and told me that i had blown some electronic thing or something in it hence the car turning itself of. is there any chance the cas has shit itself around the same time or do you think the ignition dude has pulled the wool over my eyes?

[Brett_jjj]

They are a pretty common thing to fail,I wouldnt jump to any conclusions about the ignition module bloke,but you never know.Just be wary,and if you are not sure about a service or part, then always get a second opinion,and post it here as well.Someone here will soon tell you if it sounds right or not. Cheers.

I just realised your VS is a V8.Im pretty sure they dont have have a crank angle sensor.Sorry about that mate,leading you down the wrong track.Ive read on here that a few people are having trouble with the V8's ignition module you mentioned.And it causes similar problems to what you have had. Id get another one from the wreckers.Try it and see how it goes.

I think the V8's have a hall effect sensor instead of a crank angle sensor

Oh okay is it hard to find/replace? its near or in the dizzy right?

[sydsider66]

Its the fuel pump.Same thing happened to mine.When it stalls or doesnt start see if you can hear the fuel pump turning on with ignition for a few seconds.If you cant hear it its the pump intermitentley working.Its telling you its on its way out real soon.

Im still not even sure if they have one :P
I was just throwing it out there, because no, the V8's dont have a crank angle sensor, and I've never heard of one failing on a V8 before

In order of most likely/easiest to check/fix, I would be checking the following:

Hit the fuel tank with a hammer/big spanner next time it wont start, this should shock a failing pump into working again, so if it starts after that, you need a new fuel pump. Spark at the Plugs and Leads, Fuel at the fuel rail, Replacing fuel filter in case it is blocked, Replacing fuel regulator. It could also be a dodgy ignition module, even if you only just replaced it. Maybe see how much a wreckers is charging for a used one and test this first before you throw money replacing things like the fuel regulator, because you cant really test a regulator, so its replacement or nothing, and they arent cheap.

Apart from this you start looking at small electrical things, or a buggered ECM.

Send it to the naughty corner.

[Dinwoodie]

Send it to the naughty corner.

I did, refused to offer ice cream after dinner too banned all tv and still no luck.

Its definantly not a fuel problem it does the same when i switch it to gas. I've replaced ignition module, dizzy hall effect, coil and still have the problem, its gone to the auto elecs now so ill let yas know what happens incase someone has this problem they can sort it out without having to go the extremes like sending their car to the naughty room.

The Auto elec thinks its the BCM but he wont know untill he goes right through it!

95 VS V8, petrol, stock standard. Starts when dead cold. But run it for a short time say a few metres or a few hundred. Switch off. Come back. Try to start. You might fail fail on the first turn of the key. But it sounded hopeful. Second turn of the key is totally different! No possible hope of starting! Only hope: Turn ignition on. Floor the accelerator and hold it there. It fires immediately, and you have to back off successfully to keep it going. If you don't get it started, walk away, and come back when you think it is dead cold again.

hey mate how did u go u find out what the problem is im haveing same problem with my 5liter had racv out still didnt have a clue and im chaseing around 4 a ignition module to c if thats the problem

[dirt drifter]

my 5L vs did something similar a week ago, died while i was driving. had fuel, spark and injector pulse but no go. after 2 hours it fired up again. turns out the negative lead was loose at the engine. might be worth checking that you've got good earths and the cables are still in good nick

Yeah, mine failed with similar symptoms to those described. I'd be looking there. However I am confused as he states he replaced the hall effect sensor. These are no longer available separately and haven't been so for some time. New dizzy only.

Are you sure you have replaced the hall effect sensor?

[BottleFedVS]

I replaced a hall effect trigger and they are still available through some parts shops for about $35-$50.
It is a Barstard of a job though.
