No Spark on Bank 1 - Ionic unit??
Recently had an issue with the vanos oil line bursting, causing the vanos oil pump and solenoids to have issues. I replaced the vanos oil line, cleaned out the system, cleaned the pump and vanos solenoids which are now in working order. Gave the motor a crank, it started the first time (rough as I didn't do the vanos bleed yet). HOWEVER, after turning off the motor the first time, it will no longer start back up. After multiple checks (no relevant error codes), I can see there is no spark on Bank 1. I replaced the ionic control unit, still no spark on bank 1. I swapped sides with bank 2's ionic control unit which had spark and still no spark on bank 1. Any suggestions or things I can check? It is currently not starting at all.
