A freind has a similar problem, only thing I have found so far is the wire loom coming out of the ECU case (behind the battery) goes through a plastic clamp, the clamp had pinched the loom and 2 wires were near enough worn through. Fixing that made it a little better, but it is still difficult to start and lacks power too for some reason, I am getting my hands on it next week so if I find anything I will post it here.
