hi im doin a rst conversion on a mk3 xr3i, ive put it in myself and done the wireing myself im ok with most stuff but now im stuck, the engine cranks over and wont start the fuel pump is behaving normaly, if i crank it ,open the thottle and push the metering flap down it will run albeit not very well and lumpy if i let go of the flap it cuts out i can find any obvious air leaks, im not very clued up on rst,and have searched the forum ,but no joy

also theres a pipe coming out of the side of the metering unit near the boost pipe but not the breather one and wheres the fuel pressure reg vac pipe go to, im having a mare because ive bought all the bits individual and didnt take em off car
any help appreciated
