I have just brought a 1983 XR3i as a project, but seem to be having a problem with the K jetronic injection system, the car struggles to start, can't idle, rough on acceleration when it does.
it has a new fuel pump and filter, when I discount one of the injector pipes and the jet end, nothing seems to come through, But is that because it is no longer under pressure ?. Also discounting the unions that feed the injectors, only a little fuel weeps out, but at the cold start and warm up regulator, the unions are under pressure.
is the metering unit at fault and is there a easy way to test it ?
any help please.
Thanks
Clive
