I have had a look at it today, checked spark..ok. So slackened the banjo bolts for the injector pipes and primmed the pump, alot of fuel came out with out cranking the engine?

Removed the plugs, and when cranking lots of fuel comes out the spark plug ports!??

Came to a conclusion that whatever controls the fuel for coming on boost is stuck wide open???
And is flooding the spark out before it gets a chance to start.....
Obvious thing to do is change the metering head and try it, but just wanted some advice.
Any ideas anyone????
