HELP!! My Audi S2 still wont start!! :(

[eXtreemeRS]

Hi!
Got a Audi S2 2,2 turbo 92mod.
The car just stopped one day..I suspect the electric..
It seams like the brian of the car dosent get 12v power..
Anyone got a manual of the wiering form the fusebox and out??

The fuel pump should start for a few sec when I turn the ignition on..
I dosent.. There is no sparkel out from the coyl..
But I can open the rele for the fuel pump and start it manualy.. then I can hear the fuel pump start.. but the car still dont...

I have now changed the fusebox and all the fuses + all of the rele's.
I have changed the ignition lock.
I have checked the Hall sender, and it's ok..
I've replaced the controll unit (the brain)

Anyone got any idea's???

Replacing is good, however not perfect solution.

I suggest you, check what is going on. Take electrical schematics, and check what is ECU seeing in terms of voltage and ground - I mean check the connector pins with ignition on, ignition off. Most of testing can be done with simple multimeter. After that try to read ecu errors using some VAG-TOOL, or just read the blink codes (you will find info how to do this in pages below). If ecu is OK, and voltage and ground inputs are OK, it will tell you, what is wrong. BTW don't be scared if ECU will give single error "Crankshaft reference sensor blah blah", it should disappear after you make several turns of engine with starter.

Do u know where to get the VAG-TOOL??

Make you own, lend from someone, buy . There is number of options. My friend makes those, so I don't know where to get them elsewhere.

I suggest you to visit http://www.s2central.net/blinkcodes.html page for blink code info.
It contains information what to connect, where to connect in s2.

Good luck fighting that gremlin, which made itself home in your es2 .

hmm.. so the VGA-Tool is not a software that I can install on my laptop..?
Is it a external box? sure I can build one, but need instruction manual on how to.
I'll enter my garage at this time.. if im stuck.. maybe I can
hook up my cam in the garage so u can watch me blow up the car..
hehehe...
anyway... of to the garage!!
