Good evening,
I have made the anual oil change and took the opportunity to sort a leakage at the oil pump. All three o-rings have been changed. Everything is installed now and when I turned the engine without ignition in order to fill everything with oil and build up oil pressure the gauge needle remained at zero. I opened the pump relief valve in situ in order to check whether I made a mistake during reassembling. No, everything is ok. I srewed the spin on oil filter off and (appr. cup full of) oil came out of the oil ways/gallery. So the pump does feed but with or without pressure.?
My questions:
--is there really no oil pressure or is the pressure gauge/pressure sensor faulty?
--how can I check the two VDO units? When I started the winter brake for the Stag 6 weeks ago I didn't watch the pressure gauge so I don't know whether it was indicating pressure or not.
Here is the VDO wiring diagram:
-any further ideas and help are highly appreciated.
