I'm building a cosworth powered mk2 Rs2000, if fitted engine wired it all up etc

Car will run for 1 or 2 secs thats it, it only runs if distrib is turned clockwise of the mark inside!

Engine timing is fine, compression 120psi, fuel pressure 45psi, excellent spark, fitted new TDC sensor, Phase sensor and ignition module

i pulled out injector rail the don't seem to be firing quite right, any way of checking sensors, what about a self test?
