yuck, talk to Ryan Parkin here:
1.9 8v TDI PD150 (ARL) Injector Set - 038 130 073 AL - Darkside Developments
He'll ship them over stupid fast and they'll be cheap, you'll need a tune for that set specifically, otherwise check tdiclub classified for a set ($300-500)
Is it a MKV or MKIV? MKV PD injectors are different than the rest but you can interchange a whole set and they sometimes need a tune to work properly(different size plungers, etc)
-edit- Why does he think he needs a set of injectors? I bet he doesn't. I bet the harness or something else went bad, unless he dropped them or something.
