I recently had to replace my clutch slave cylinder on my Saab. Before that, the car was starting without any problem. After replacing the slave cylinder, the car won't start anymore. The crankshaft position sensor is good(getting rpms while trying to start), fuel pump is good and the starter motor is running but the engine won't start. Note that I didn't start the car for 1 months approximately as I was waiting for the parts to arrive. I checked the ignition cassette and only bank 1 and 2 are getting sparks. I tried another ignition cassette and the results were the same only 2 banks getting sparks. Is it a ground wire issue? If so where should I start checking?
