[s-cars] Non S-car start problem

[seanupchurch at comcast.net]

Have a co-worker whose son has a 1993 90 Quattro V6 and he is having a little problem crank starting it.  The guy knows cars  but is not familiar with Audis.  He cannot get the car started by using the key.  It turns over, has plenty of juice, is getting fuel at the rail but engine will not fire.  The car will start if it is pushed down a hill or pulled by another vehicle.  I suggested replacing ignition switch, thinking that switch is not activating ignition system 



Any suggestions?  He does not know if plugs are getting spark when key is used, will be checking that tonight. 



Thanks,
