Question about 1997 Audi A4
#2 coil not getting signal
I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

Mine was running fine driving 70MPH on the highway and just shut off. Now it cranks, fuel pump runs and it seems to be getting fuel but still no spark. I have a coil/module on order and will try it tomorrow.
Replaced the coil. Coil sparks once when you first turn the key on, that's it. crank sensor has already been replaced yesterday.
Injectors seem to fire (I smell fuel if I crank it a while) but still no spark.
I have 12V to the coil and 12V when cranking.
I see tons of posts with this issue but no resolutions. Come on somebody has to have been here before....
I do NOT have an injector pulse or a pulsed signal to the coil. When I crank the car the oil pressure light blinks on and off (just noticed this not sure if it is relevant)
I do get a check engine light when I turn the key on and when cranking, thought this meant ECU was good?
Any other way to test the ECU?
Could the pick up in the distributor be bad? Doesn't the pick up signal the ECU to fire the coil and injectors, I thought the crank sensor was just a TDC reference point?
