What for god's sake is WOT?
Idle switch does sometimes do a lot to fail the start, NO signal to the injectors seems to me a bit to nasty - but not inpossible.
Did I understand you right? you used a other ECU and faild further? or do you mean you would try a other ECU?
At the moment I would say, if any responsible sensor fails there shouldn't be fire nor a signal to the injectors. Maybe I'm wrong..... I think not
Oh... do you check the second fuel-relay?
