Hi Gregson944,
When the engine turns over, can you hear a "clicking" noise coming from the glovebox area similar to if the indicators are left on? If so this is the factory fitted immobiliser working, it is located under the wooden kickboard on the passengers side, next to the ECU.

I had a very similar problem to yours a couple of weeks ago, Does your car have the Leds in the door locking pins and have you had the door handles off or oiled them?
Because on mine I had upset the switch located in the door locking mechanism that is used to turn the immobiliser off and it would not start Just turned over as normal(posted thread on here) Hope this helps.

Where in Wolverhampton are you?
Jon

No problem, I was just grumpy after making the effort to log on (I originaly read the email subscription), thats a bit far for me though []

Have you made any progress?

Hi Greg,
It appears that you have two alarms fitted, the factory fitted immobiliser and the sparkrite one, I would suggest that it is the factory fitted immobiliser thats causing the non starting.

The immobiliser is switched on and off by a micro switch located in the drivers door handle central locking mechanism.

I would first check the opperation of the central locking system on the doors, ensure that red Leds in the locking pins go out when you unlock the car door and then check that they start flashing again when you lock the door and that the doors are physically locked and unlocked.

Next lower the drivers side window, close and lock the car doors wait untill the Leds start flashing and then reach through the open window and try and start the car, you should hear a "clicking" noise coming from the glovebox area, if so this is the factory fitted immobiliser working corretly.

Now repeat the above process but this time with the doors unlocked, you should NOT hear the "clicking" noise coming from the glovebox area.

If you do, it is either the immobiliser control unit or the door microswitch that is causing the problem.

You will find the immobiliser control unit located under the wooden kickboard on the passengers side, next to the engine ECU. Pictures and instructions on how to bypass can be found on clarkes garage (http://www.clarks-garage.com)

On mine it turned out to be the door microswitch that was causing the problem.

Depends on year - on my car (1990) the door switch dissarms / alarms the alarm only, the immoboliser is controlled by a push in 'key' on the column. When the immoboliser is armed the starter wont turn, from reading Gregs first post it sounds like it is turning over but with no spark - could be a partial failure of the immoboliser - what make is it? Could also be coil / rotor arm related or down to the flywheel sensors.

Car Alarms only inconvenience the owner never a thief - thats my experience any way.
No-one takes any notice of the alarms. The neighbours get upset when they go off at night.
They leave the owner stranded.
No-one can fix them, just fit a new one.
The stupid contraptions dangling on the keys are a pain to use, especially in the dark.
No one else can borrow the car or even move it with your permission because of the complicated sequencing of buttons etc.
Finally, the fitters never wire-connect to a high standard, cheap crimps, butt connectors.....
Rant over - really I dislike the things.

I hope you get to the root of the problem Gregson, - perhaps it will not be the alarm.
I once had 2 alarms fitted to my 944t - a nightmare.

John when you were looking at the drivers door key switch problem did you find a wiring schematic ?
My 89 S2 has an electric switch connected to the rear hatch which was always the vulnerable point on the Lux. I was wondering if that switch could cause a problem with the alarm/imobilser system.Is it part of the alarm system?
Like George I'm rapidly coming to the conclusion it would be best to strip out the original alarm system and the two imobilisers fitted to mine and install a complete new system. I think I'd fit it myself though . After seeing the `workmanship' of auto sparky's

Hi Peanut,
Sorry no, I did not have a wiring schematic, all I did was clean all the oil off the switch and make sure it was orientated correctly, with no lose or broken wires.

In regards to your switch connected to the rear hatch I would suggest it is there to trigger the alarm like the bonnet switch, rather than to arm or disarm the alarm system.

Totally agree with you and George on the removal of the multiple alarm systems that are fitted on most 944's, latter on in the year I will be contacting Jon Mitchell's garage in Bournemouth, hopefully to have him remove all the alarms on mine and fit a new system with remote locking.

Hi Peanut,

I'm going to have to get to the bottom of how it works as my hatch won't pop on the key. Something should trigger the hatch lock motor and I assumed this little microswitch did that ?

Why is it we don't have a decent clear schematic for the 944. ? most of the ones I've seen are dreadful, non scalable unreadable. grrr
