why won't it fire???

[aerosam]

Ok for those not in the know, my car has a BMW M60 3.0L V8 installed.

Tried to get it running today - and failed.

After several hours going over the wiring with a multimeter I can surmise the following.

the starter is cranking the engine
the fuel injectors are working
the spark plugs are firing
the fuel pump is pumping
there is fuel in the tank

I am getting fuel vapour ejected from the exhaust ports, and the (very) occasional cough of life. WHY WON'T IT JUST START!!!!

Have I missed something obvious?
