My mates putting together an xr2 turbo with MFI rs turbo engine.

We've been trying to start it but with no luck, theres a spark there and the car fires and fires and fires but just wont go

We've done all the basics like checked the timing ten times over, checked for air leaks etc etc.

Only thing i can see is theres loads of fuel pressure at the filter, but when you crack the nuts off on the top of the metering unti you only really get dribbles of fuel. so we took an injector out and fuel will just come through when the flap on the metering unit is fully depressed, is that how it should be ?

Anyone got any ideas ?

Cheers.
