When you crank the car over the tach needle should jump off the stop

Not sure to be honest on that, but I'm thinking it might be the dme relay after doing some reading, the symptoms I'm having do seem to point to this , was wondering if it got wet with this water coming into passenger side. Car is now under cover to keep any further rain out.
Appricate your help and advise on this.
Will try and locate the dme relay tomorrow.


"Not sure..."?.... OK...when you try to start the car does the tach needle move like 2 cm, if not it would point towards bad ref/speed sensors or DME relay..............http://clarks-garage.com is a whole world of free help.......but it does sound if you have severe water ingress this will be the main source of your problems........keep going......you will get there :grin:

Glad it's sorted, the DME relay is the one spare you need to carry with you in the glovebox.

I'm having the exact same problem.
The car's been sitting for about 2 weeks under a cover outside in all the rain and snow and frost. When I tried to start it, it turns over but doesnt catch. the rev counter is moving a very small amount, about a needles width. tried a few ideas which didn't work out.
Got two new DME's coming this week (one for spare) and the battery is on charge in the house because I tried a bit too much! :dope: :dope:
Such a shame too. That car has never failed to start on me until now. I should've grown bigger balls and taken it out in the snow!

Just solved this problem.
The battery negative cable maybe the cause.
It is really hard to access so try a link to the battery direct to the engine.
If you can hear the solenoid clicking on start position on the key switch it could be the starter motor.
You can normally hear if the fuel pump is working on accessory position on the key switch.

Other things might be :
Badly fitted or old immobiser.
Bad key switch it is a VW polo etc on mine and not as advertised in the 924S parts manual.
The battery is no good.
Rodents chewing the wires.
