Hello mate,

Really sorry i never got back to you with the metering unit you asked about, it seems to have gone missing but i could have always shoved it in my lock up and forgotten....

Any how, if you have tried two metering units with no joy, i suspect your problem will be with a fuel regulator (if the same one was used both times), fuel accumulator or the fuel pump. With the plug disconnected from the black box on the side of the fuel distributor fuel should still come out of the injectors when the flap is depressed.

Is it possible that both meting units were pants?

Rob,
