Well, things aren't going well.
I've replaced the B8S6 relay, coil pack and CAS, checked belt/timing alignment (in line and 19 teeth between Mark's on the belt) and the car still won't start.
I'm now thinking maybe my fuel settings are off and my yellow Denso RX8 injectors (# 195500-4450) maybe flowing more fuel than anticipated although I've 195500-4450 increasing the injector size/reducing req. fuel in the MS2 settings (set at 425cc/6.4 as standard, with dead time set to 0.8 - no longer sure this is right with the new walbro 190lph pump installed?), but no joy.
I may have to pull the injectors and get them flow tested.
It may also be the ignitor I guess. I need to slowly check everything again with a multimeter.
