Had another crack at this last night.

Oil on dipstick like new but oil in new oil filter dirt black so that told me oil was circulating with electric pump.

But when tried it off starter was cranking too slow so that meant battery or cable issue & not sucking oil from pickup.

Full charged battery & jumper pack still turned too slow put multimeter on 12.5 volts after lot of cranking but when under load dropped to 3 volts on battery & 7 volts jumper pack connected yet still turned engine over lol.

Right as about to give up oil was seeping from oil pressure guage & went halfway up line when battery totally died.

Next step new battery obviously & get some reco'd injectors so can jerry rig a fuel setup & hotline ecu to run.

If oil was moving up the line then you have pressure from the pump.

That is why I've moved on to wiring & fuel side of things will send injectors away to be cleaned & serviced.
