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?
