My problem started when the car started misfiring quite badly. I then pulled over and turned the engine off. I then tried to start the car again but it would just crank. I had to tow the car back home. After checking I realized that there was no spark at all. I then bought a new coil pack. I installed it. No spark still. Then I did some research and I managed to test the pulse going to the coil pack. I was only getting a pulse on one side of the input to the coil pack. The other side was dead. I did more research and I was directed to the ignition drivers. I replaced both ignition drivers in the Bosch ECU. Tried again and no same problem.

Could it be the crank position sensor? But why am I getting a pulse on 1 side of the coil?
How do I test the crank sensor?
