How are you guys diagnosing the CAS problems? Is there a voltage available or drop test you can do? How about a ground test or resistance test? let me know , right now my 90 tsi awd with a 92 wiring harness is having a no start problem. I have 165 compression across the cylinders. I tested the fuel pump and get spark once in a while.
I know my mpi relay and ecu work also because i tested them out in another car. finally but not least I have available voltage at the injector clips but when I try to turn on the car it seems it is not been grounded.
I am leaning towards the CAS and the injector resistor, but I want to diagnose these problems without going through all trouble of taking these parts out and trying other known good ones.
I have diagnosed a couple of no starts but nothing like this. I just wish I had more money to buy the "special tools" to diagnose this problems more accurately.
