The 135 telltale light is the engine management light

Thanks for that I take its the flashing one when you check the codes?

easy way to see if chip working take it to key cutters and say you want a key cut, they pop it in and then tell you if its work and how much, and say no not at mo and leave. did it other day. as vauxhall wanted £30 just to test it.

Sounds like a cunning plan I will give it a go tomorrow. If the chip has failed can a new one be fitted and hey presto car immobiliser working again or is that just wishful thinking???

I didn't think of that I take it you mean have the key in the ignition and turn to position 2 then try turning on the key fob and see if anything happens?

yes then take key out and try buttons see if the doors lock-unlock. it should start then. if locks working.

I think you are confusing the early infra-red fob with the later wireless fob.

The early cars had a little black dome next to the sunroof knob. When you press the unlock button the led on the key fob has to be pointing at the dome for it to work. After unlocking the doors the immobiliser is disabled for about 30 seconds to give you time to start the engine. If you don't start it in time you have to point the fob at the sunroof again to disable the immobiliser for another 30 seconds.

On later cars they switched to a wireless fob (to unlock the doors) and fitted the immobiliser in a plastic ring around the ignition switch. The immobiliser senses a tiny microchip in the key. The microchip quite often falls out when people are fitting new batteries to their key fobs  . If the fob battery has been dead for a long time it might be necessary to resynchronise the fob with the car by turning on the ignition and pressing the fob buttons. (This won't work if the key has not been paired with the car first and probably wont work if the immobiliser chip is lying on the floor somewhere................) Resynchronising only affects the remote part of the fob. The car should still start even if the buttons don't open the doors.

Yep, immobiliser and remote fob are completely separate on later cars.

IIRC, the EML flashes when cranking if the immobiliser hasn't disengaged, though. And I believe the engine will fire and then die, not just crank over endlessly.

It would be useful if you told us the age of the car as that will help determine whether it's a pre or mini-facelift car or even facelift car.

Hi there,

My thanks to everyone who has posted. The car is a P reg 1998 carand is a non sunroof model but the gentleman who provided the info on sunroof models it wasn't very interesting to learn about that.

I have a seperate key and fob and the fob has 2 buttons on it unlock and lock and they light green and red accordingly.

Anyway getting back to mine. Today I fitted a good fully charged battery and left the car for half an hour and when I went back to it I did the following.

I locked and unlocked the car with the key sat in car and put key in ignition to position 2. I then tried and Succeeded to operate the key fob and the doors locked and unlocked with me in the car.

I unlocked the car again with the fob and then I tried to start it, Sadly it still didn't fire up and the orange(yellow) light in front of me stayed on all the time I was cranking Its shaped like a pump with an electrical flash in the middle so I take this is the EML light?

2 other lights also stayed on whilst cranking the red battery light and the oil level or is it an oil pressure light?

I rechecked the oil level which is fine.

I did not see anything missing off the ignition barrel i.e. the the ring so it now seems although one step closer it still won't start.

Should I do another paperclip test and if I remove a fuel line will it show fuel pumping through?

Someone mentioned the crank sensor do I have to jack the car up to access it? as the book shows it by the oil filter?

I look forward to all your advice and thanks again

P reg and 1998 dont go together...

If its the old IR style, and it is an immobiliser issue, then it is quite easily resolvable

[I_want_an_Omega]

Might be a silly question, but this is Vauxhall as opposed to an Opel badged car isn't it?

The reason I ask is that ALL retail 3.0 Vauxhall cars had sunroofs. Is this an ex-Police spec car?

[freecall666]

are you sure it was running before it was garaged, seems funny that it has not been started for 8years?, i would see if some one could have a look at it with propper tec2 and see whats wrong with it if you ask some one on here may be able to have a look for you. and just a quicky, when the doors are locked dose the red light for the alarm flash 30 sec-60sec after the doors are locked. also have you had the plugs out and see what they are like?...

What is IR style being a p reg it could be 97 but if it is what you say it is how do you resolve it?

Yes this an ex police car as I was informed by the previous owner and although the car was put away he did start and run it from time to time and said everything was working fine until he le it run out of petrol. I have put fresh petrol in
