I have a 2000 Audi A4 quattro with the 2.8. Started it up this morning and drove it less then a mile. Tried to start it after about 10 min and now cranks good (12V at battery), but it is not getting any power to the coils. There is also no pwr at the fuse (good fuse) either. Please help.

Thanks, Kelly

 

I assume you checked with power on ?
If so there is an Ignation module/senor on the air box that controlls
Spark this things mostly go...
Check that out
If not check out all the Inputs for Ignation, Crank Sensor, Cam Sensor

 

Yeah I checked with the key in the on position. The thing finally started after about 3 hours of messing around. I checked a bunch of connections and tried checking temp sensors and other easy things. It looks like the only thing by the air box is what I think is the mass air flow sensor. I don't think this problem is fixed yet. Is this ignition box you mentioned able to be tested?
