would this stop the car from starting. just got my s1 and it aint going. the guy had running issues with it, it was missing. he put plugs, leads cap etc, no difference. then there was no fuel getting up to her so a fuel pump was fitted.

car started and ran fine, then started missing again, now she wont go/

whats the usual symptoms of a faulty metering unit?

i cracked the fuel pipes at the top of the unit and wound it over, not much fuel squirting out, i wound have thought it would spray out?
