I hadn't seen this specific thread before, thanks for trying to help, but I have tried battery disconnects, ECU disconnects, pedal dance resets numerous times, hard reset, ECU reflash that really should reset everything and still not perfect yet. Thanks though, appreciate all help and contributions.
Reading that last bit of the post bizizl highlighted, the last step is a curious one.
"I redid the pedal dance for learning the trottle position. This time I did one thing slightly different though which I suspect was the previous cause of all my problems. After releasing the accelerator pedal when the engine light becomes steady I just flicked the key one more notch to start the engine rather than through force of habit been turing off then on to start the engine."
I could easily see myself getting this key bit wrong and turning the key to off, instead of pushing it straight on to start. Good spot
