the only button in in your glove box is the boot release if it has factory fitted security system it will have a lock which can arm dis -arm the alarm
unless someone has fitted an aftermarket alarm system and have actually put something in the glove box.do you have a remote for the system? other wise if not alarm system may not be your problem,could well be a number of things from fuel pump to crank angle sensor

[lord_davros]

you could always try resetting the ecu.. disconnect the battery and leave your lights on for a few minutes.. worked for me last night..

[william19]

it has a remote for an alarm sytem which i have not used

i have replaced the switch on the transmition, and it went good for a week now no start local mechininc said ignition switch so i replaced it still no go now he is telling me it has to do with the alarm and i need to have all the wiring disconected i have no idea what i should do next it is so frustrating when there is only one mechinic in town,

is there anyway of testing the crank angle sensor you mentioned?

i have replaced the fuel pump about 5 months ago,
at the same time i put in a new reco motor i have put so much money into this car

Checking your Computer for Faults (VN - VP)

Have a read of that, it may shed some light.

when you put key in ignition and go to turn it over,does anything flash on your dash or anywhere,i'm assuming dash as thats where factory fitted alarms have their remote warning light,also when you go to crank car over or even if you have it on accessories does the engine light show,by that i mean does it light up,if it does...it's nothing to do with alarm or immobiliser,just for curiousity sake check your engine fuse under bonnet.

[william19]

dash lights come on one is a (!) it is a red light what does this stand for i dont know a great deal about cars,

i have checked the fuse all good and what does the engine light look like

[samuels]

turn your ignition on....look along all the lights that light up on the bottom of your dash...look for an orange light with a shape of an engine inside of the orange light,if this is glowing,thats why i say it's nothing to do with your alarm,as you have to use your remote to disable engine immobiliser,once it's immobilised the orange light comes on

[william19]

yep the organe one comes on

[pow3rslave]

it's probably not the immobiliser then, when you turn the key to acc, do you hear a faint hum coming from the back of the car near the fuel tank for a bit?

[samuels]

yep the organe one comes on

sounds like there is no immobiliser working if your engine light comes on(factory fitted ones do this-not sure about aftermarket ones) i do know with aftermarket ones,as i have a VN executive as well,it has an aftermarket one fitted,but i haven't paid much attention to dash light on that on,i'll check that out in a minny have to shift all the cars about to let missus out.....but in that one,they have the little flashing light mounted on the steering column shroud,press the remote just like factory remote,indicators flash twice for dis-arm,and away she goes,i'd imagine the engine light doesn't show when i turn on ignition,not until i dis-arm it,so thats a sign to me,that the alarm has nothing to do with your car not starting as by the way you are explaining,it comes on with out using your remote,only other thing if you think it's still alarm related,something may of happened and needs re-coding,but you said it was going before didn't you?

[william19]

yep the fuel pump comes on
and before it was going and i had the switch on the gear stick replaced
it went good for a week then it would only start every now and then say you turned the igntion 10 times to get it to go or sometimes turn it once but now not at all thats why we replaced the ignition switch and barrel,

there is a red alarm light that flashes it is under the steering wheel, and there is a black button there that i have had to press before when the battery has gone flat the previous owner said thats what u do otherwise it wont start,

is there anyway you can disconnect the alarm to see if it is that?

[william19]

quick question surley it would not be as simple as the battery ? would it ?

there is....but it requires you to unsolder the ignition wires under steering column and join them back up to original wire it was snipped from(leaving immobiliser wires off...obviously),from memory there is only 2-3 wires to snip and join,join them back to original colour coded wire,then take out drivers side kick panel,there should be wires soldered into fuel pump loom,don't have to cut them....just bridge them,then see if it will start.if it starts...your immobiliser will need recoding.
weirder things have happened....i'm just wondering if because you put in new ignition switch and barrel,it has to be all recoded
so is that light flashing now under the steering wheel?
also who fitted safety switch to gearbox? may not of been fitted correctly, or you was sold a brummy switch

only the VN calais had the factory alarm/immobiliser. after market alarms don't effect the engine check light like the factory alarm. he says the fuel pump does hum when turning the key to the "on" position so the aftermarket alarm thats fitted doesn't interupt that circuit by the sounds of things. try moving the gear selector to the nuetral position "N" and try starting it, if not try moving it whilst holding the key to the start position. to test the starter motor circuit turn the key to the on position (make sure it's in park withthe handbrake on etc) and then pull the starter motor relay and use a short bit of wire to jump accross the 2 pins to run the starter motor etc. if the starter does turn the motor over and start the engine then you know the immobiliser is interupting the starter circuit. either fix the alarm fitted or remove it etc

from memory thats how all aftermarket immobilisers work,connected to fuel pump,so maybe has been disconnected,and like i said in my previous post,i'd be looking at the transmission safety switch again,even the start relay under the bonnet,if it has an air conditioning or something that isn't required with motor running swap it over into the start relay terminals,as they are all nearly identical

[william19]

ok thanks i will try those things asap and the local garage fitted a new gear switch
how do i re code?

and what does a red light on the dash mean it looks like this (!)

theres 2 that look identical to this one if it has a circle around that exclamation mark it means brakes...however the other one,that looks like the one you have diagramed here...well i haven't come accross that one yet,and it's not in any of my service manuals or even any of my handbooks on the VN's..so i can't help you with that one sorry.
as for re-coding...if in fact it is your immobiliser up the putt,thats a job for the auto electrician,unless you have the paperwork that came with the car about the immobiliser,it should have step by step instructions on how to recode your immobiliser if any need arises

[william19]

ok thanks for the help
one more question would i be able to jump start it?
cause the closest auto electrician is 100km away

you can...with jumper leads with surge protector between the jumper cables,but before you waste heaps of money,how far away is your local mechanic? would he be prepared to lend you a good second hand safety switch for the auto tranny.have you disconnected the immobiliser,if thats all disconnected,by rights your engine should start...if your immobiliser is defective

[samuels]

[Quote] it has a remote for an alarm sytem which i have not used [Quote]

what do you mean by this? if i'm understanding correctly,you have to push the button on remote to disable immobiliser,then engine should start....if you haven't tried this,try pushing a button on the remote,have the remote pointing towards drivers side door,see what happens

[william19]

by remote you mean central locking black remote
if so this stopped working months ago and i just use a key to open the car

one weird thing the car does is when you start it it locks all the doors

[william19]

there is also a half a key that came with the car with a hole in the end of it is this something to do with the alarm

some older alarms only had a single immobiliser circuit so you could choose which circuit to interupt. by using the wire to short the pins in the relay base you can bypass the imobilised circuit and run the starter without using the key. the reason i suggested putting the trans in nuetral and then moving the selector whilst holding the key to "start" is and easy way to see if the neutral safety switch is set/adjusted correctly. swapping relays is a good way to test for a faulty relay but with the little red light flashing i'd suggest that the alarm/imobiliser is armed etc
