as most of you know i now own an Audi S2 with the 5cyl 20vt ABY engine. i bought it from an auction damaged and it was probably sitting around for months without being started. so now it doesnt start. it cranks over but doesnt fire up.

where should i start looking? i at first thought the coilpacks but even if one or two of them are dead it should still run? but yeah... no clue about these engines so somewhere to start would be great if Jmac or Seb or Matt or anyone who is clued up could give me some pointers

cheers much appreciated.

Yep mate ok when the engine is cranking is the fuel pump buzzing??????? Check in the plenum chamber , this is where the fuse box is. The cover will give you a description where the relays are if you get stuck i will give you the location, just im at he mother in laws at the mo , will be in later. Remove a plug check for a spark. Does it sound like it has compression?????? What kind of hit did it have?????? No damage to timing belt cover????????? Remember man start at the absolute basics. Good battery, check for spark, check the pump buzzing , if it is crack a line and see if you are getting juice. Fuel air and spark at the right time and that baby will go. Fuel pump relay also gets an earth pulse from the ecu, you can trick this too if need be but like i say BASIC 1st, then we will dig. Ah yes and a compression test - remove the fuse for the ecu. Might just need some oil down the bores mate , gassed up plugs and crap fuel the bores might have a wash.
Chime if any dramas
