PLEASE HELP no fuel to inj 3 and 4
My escort turbo MFI is getting no fuel to 3 and 4.

At the moment nothing is happening on 3 and 4 is kinda working. When you take the plugs out they are covered in soot. pot 1 and 2 are spot on and running as they should. Feul pressure to the metering head is 6 bar.

I have done a compression test and all cylinders are at 150psi + so no issuse there.

I have tried 3 different metering units and no joy

All 4 plugs are sparking and i have no air leaks.

Car has 22 litres of fresh fuel in the tank.

Please can someone help as i have run out of ideas
