got a fuel problem, don't think its getting past the metering head, is there a relay or fuse for the metering head?

Was told it was fuel pump, so changed it
Checked the fuel pump, thats working (can hear it)
Put petrol in the inlet manifold & car started for a while
Changed the fuel filter

 

have you checked for air leaks? have you tried pushing the flap down slightly in the metering unit while someone cranks the engine over?
