V8 EDIS MS Non start

Further down the path, but still not running. I've posted a video here http://picasaweb.google.com/lh/photo/L9u17vskyu3gjg9dHabvhg?feat=directlink (pick the HQ option) to show what's happening.

The HP fuel pump primes, I crank the engine and the injectors inject. Sparks spark but the engine doesn't start , it tends to bog down, goes 'phut' and something blows out of the inlet manifold.

What is the most likely thing(s) I've stuffed up?

Regards,
Dave

Definately got 12v to Megasquirt/edis/coilpack/fuel pump when in crank? (not just run)

Spark plugs wet ?

Can you put up a link to your MS map.

sounds like its sparking too soon.Chect the cranking settings on the MS

are you 1000% certain the VR sensor is in the correct position on the trigger wheel.

I am still a few weeks off starting mine.

Thanks guys. I found I had the sides of the coils crossed (A was B, B was A, C was D D was C) which was probably the cause of sparks with the inlet port open. I also had a small leak of petrol and managed to spray myself with petrol fixing it so I've given up for the night now I've had a shower
Right now I suspect pretty much everything I've done. Timing may well be out as I based the trigger wheel position based on the marks on the damper. I assume this is probably correct as it is located by a woodruff key. I'll try again tomorrow.
