The best test is to get all 4 injectors out of the inlet, then screw them back into the fuel lines,
Tighten everything back down on the metering unit.
Disconnect the CSV (electrical plug)
Place the 4 injectors into some kind of container (a pint glass each or something).
Then crank the engine and observe the spray patterns.
If nothing, or a dribble, then lift the metering unit plate slowly (and carefully) - found under the rubber boot. Again, see what happens at the injector end - pressure should rise rapidly if the MU plunger/ports are working as expected.
Thanks for the quick reply, is it possible to try lifting the metering unit with just the one injector out? just tried the one injector with the csv disconected and still nothing. Also taking all 4 out would take me a while like u said there hard lol and also would have to remove warm up reg and bracket. cheers.
I tried it with just the one out but still nothing, my plates already stuck up and when i press down it sounds like a tin can being scrunched up.
