If the ECU earth is the smaller one that goes under the manifold then yes its on.
Ok, going to do the basic air, fuel, spark, and compression tests tomorrow then read for any codes with the paper clip trick. I don't see compression being an issue as its a new build. If it is, ill cry
Also remembered two other little bits of info. where the big trunk of wires comes down from the engine bay fuse box to split off across to the different directions of the engine, there is a small 3 pin grey triangle plug coming out about where all the branches split off and it not connected. The wire is only like 1" long, so something must come to it rather then it to anything if that makes sense.
Also - around where the coil, and fuse box and stuff is in the engine bay there is a small white box connected to the wiring that looks like it has a tab on it to be connected to earth. its like a small match box in size - what is this ? is this the ignitor ? I remember its just hanging, and not attached (earthed maybe). will also look at this later !
Thanks again fellas. will report back later.
