I remived the fuel distributor and took it apart. cleaned it all out and re-fitted it. this has cured the fault of fuel to injectors,the pressure is there now and the injectors now work fine. now i think i have air still in the system which i will bleed later today after work. i didn't mess with the bottom half of the metering unit with the flap though. not sure if it is good to do this?
some one on here may know more.
