HI i have an audi s2 3b model which doesnt want to start!Their is a spark and fuel getting their but the engine just wont fire up.I have the replaced the dizzy/coil/temp sensor but still no joy.The car has been in the local garage now for 6 weeks and they had no luck getting it going.Their were slight problems before however a small misfire, and sometimes when you really booted it it seemed like their was not enough fuel getting their and would just cut out.Im now out of ideas and any help would be greatly accepted, as it would be nice to see it running again before christmas!

The local garage tried to plug in but said that they couldnt pull any codes of it.Wll try and see if i can read them off with led .Checked the engine timing and this is all ok.The sparking order however seems to be all over the place.Removed all the plugs and checked them and the sparking order is very inconsistent, although the dizzy/coil have been replaced.Maybe faulty ht leads would stop the engine running, but their was no misfire or faults with the car before it stopped running!Would it be worth trying ht leads????????If not must be a fault with the ecu!And the ecu is different to standard 3b due to the conversion i think?????Anyone with any help on this one please !dean

Has it got the old plastic drive gear in the dizzy still? These are legendary for shearing off - if that's the case and they've gone you'll never get a proper spark?! You can replace the drive gear with a metal one, or replace the whole assembly with a new oneEx S2 owner, now running around in an A4 Avant quattro...
