I got an interesting exchange on the injectors (0 280 150 802)
with a Turbobricks listmember. I also found out from B&M (the
local import shop) that 0 280 150 802 is listed as US 505 Turbo,
nothing else. So maybe the web page listing the b200 turbo and
renault J7R is in error...

As I removed the fuel rail today (the two front 10mm are easy,
the two at the back require some acrobatic skills or the removal
of the fuel pressure regulator, itself held by two 10mm bolts), I
cleaned the injectors pretty good and measured the actual connectors
(and not the resistance at the white connector at the firewall, close
to the resistance pack). Reading? 2.7 Ohms. Dead on 2.7 for all
4. What's the deal here? They are supposed to be 16 ohms. They
cant be all dead at once!?
