Fixed! 'ish. Compression 150 on second crank. Catalytic converter all good. Plugs bad replaced them. Not firing on cylinder 1 and 2 so put spare coils in. Still not firing but have spark. Swapped injectors on 1 and 2 with no change... Double checked and realised the leads for cyl 1 and 2 where swapped over and now the car is running. I'm supprised that didn't cause any errors. Only issue now is that I can't seem to clear the ECU errors. There are circuit errors on all four injectors from when I was testing and one for each of the O2 sensors which where unplugged when I took the Cat out. I have a Bluetooth one and use torque pro and never had a problem clearing errors. I'm leaving the battery unplugged overnight and will see what that does. I find it hard too believe I have hard errors on the injectors and o2 Car is still a bit sluggish but assuming that's old fuel and/or engine responding to errors. Any ideas let me know. Otherwise I'll post an update.
