42 is the speed sensor Shrimp, check your dynatek connections, or pull it out and see if the quad fires without the dyna in the loop.

There is no dyna on my buddys quad.There's no spark,coil is fine

no spark at all?

43 is a fuel system voltage fault....rectifier

Ok ive double checked and its coming up code 42,which by the manual says its speed sensor,netural switch.But the manaul also says it will start,but it doesnt .The manual switch is fine and working.It has no spark

there is no killswitch tether is there, and not in all the way? weird there is no spark at all.

There is a kill switch,but that seems fine as ive already checked that.Will have another go at the quad tonight

I would double check that tether. unhook it from the ignition completely.

when I had my dynatek on, before I took the dyna off. I had the same issue 42. would turn over. No spark. pulled the kill switch off. Started right no. Not the total same scenario you're in but something to look into at least.

Thanks for all the advice and ideas  ,ive fixed it.Took the ECU plug apart and bingo 2 pins missing,one the fat orange wire and the other fat black wire.They where oppisite each other on the end.Pushed them back in and it started up first time

damn englishmen.

good news shrimpy.

   That is a common problem with the Rappy,  The main power wire for the ECU is short in the harness and pulls the pins back in the plug.  You can remove that wire from the harness to free up some slack and the problem will not re-occur.
