I'm all for trying the simple things first. It's reported that fuel and sparks are present but we don't know if the injectors are actually delivering fuel to the inlet ports. This is difficult to check but If sparks are being delivered it's likely that they are arriving at the right time because it's the crank sensor which determines this and if the crank sensor was the problem we'd likely be getting no, or intermittent, sparks. So, myself, I'd be spraying some Ezi start into the throttle body whilst cranking the engine. If it's a fueling problem then you'd expect the engine to run as long as you kept spraying. if it's a spark problem then spraying ezi start will make no difference.
At least this should narrow down whether the problem is fuel or spark related?
I think you are referring to
Multiecuscan above? and I can endorse that Gendan are good and helpful people to consult with and buy from with excellent after sales backup. I also bought from them, I think about 5 years ago now? and I have regular and very useful contact with their Grant via Email where we discuss interesting topics. I completely agree with you when you say the
MES has paid for itself over and over. In fact I think it probably paid for itself the first time I used it when we diagnosed an ABS problem on my boy's Punto - goodness knows what the dealer would have charged to sort that out!
