Have you filled up recently??? Are you sure you put petrol in??
If CPS has failed you are very unlikely to get a spark or fuel. I dont know VAG systems very well. Does the revcounter normally register when cranking? Is it now?
You could be flooding the engine if it thinks it is feezing cold and over fueling. Is it definately petrol on the plugs??? Remove all the plugs, burn them dry in the gas hob or something.
Remove fuel pump fuse and spin the engine over with the plus removed, are you getting much fuel out of the plug holes?? Leave for 15 mins or so to allow excess fuel to evaporate.
Refit plugs (don't refit fuel pump fuse) crank over. Does it cough/try to start?? Recheck plugs - are they stil dry? If yes refit again, refit fuse and crank for a normal starting period, if it doesn't even want to try to start check plugs again. If they are wet again then you are massively over fuelling, poss temp sensor.
If you have spark at the right time and and fuel of the right type/quantity then you have a mechanical problem. Are you sure the belt hasn't jumped a tooth or two giving poor compression?
