Did you manage to locate the problem? I had the same issue, never confirmed it 100% but turned out to be bad fuel/ water in fuel. It cranked and almost started, sometimes started with a lot of throttle. All sensors were working comparing to the ohm meter and I cleaned all earth points, though none of them was bad. Than one day I put fresh fuel and water treatment, and have not had this issue since. Though sometimes I hear misfire when hot, and shoots flames on full throttle but that could be another problem. It is ea82T wagon with the SPFI I think
