i am running out of patience with this car, i have spark, i have fuel at the rail, cranks and cranks but still won't start. i have replaced coilpack, engine speed sensor, cam sensor, ECU and a few more things. i get no pulse at the injectors, only two pulses at first but then nothing else. btw its a 96 quattro AAH engine, help is greatly appreciated

There are several things that can cause your car not to start like the ignition coil amplifier, it is really important that you scan your car because that will point you to the right direction. I had an issue where my 1.8T B5 would not start and it was a small resistor type thing that I found in the computer box housing



This is the part I am talking about that I found in my Computer Box housing

I would've never found this issue without scanning the car

how about fuel injector fuse? On an A8 it's under the hood.

Scan scan scan. Cars are becoming a complex network of devices interdependent on other components. Cut to the chase and see what the computer is identifying as failing. Will save time and money by not throwing money at the wrong parts.
