S2 would'nt start earlier, fuel pump was priming, great spark. Left it for 10 mins then tried again and it burst into life, allbeit a bit lumpy. She cleared her throat and I drove her home. Went out 10mins later and would'nt start.

So I cracked off the fuel injector lines on top of the metering head and cranked it over, no fuel came out.
So I'm guessing my metering unit is knackered?
Or is there a a relay or multiplug that comes loose?

 

fuel will only come out if you push the flap in the metering head down gently while cranking it over!!!

 

So if I dont depress the flap, no fuel will come out.

How does the engine start under normal circumstances then?

I'll check again tomorrow and depress the flap.

 

Hello Mate, on the back of the fuel pump (inside the large nut/19mm I think)
the is a small one way vavle which stops the fuel draining back to the tank
once the ignition is turned off. It's the same part on all the early Mfi fords
(orions,xr3i's etc) so before you start playing around with metering heads
get one from a scrappy cos even if you have to buy the whole pump to get it
it'll only be a tenner. Good luck.
