Have you checked that the turbo spins? take the intake side off and make sure it spins.
You have obviously done this before with some good results. I guess ANY ATF would work. This seems to be a plausible "try" since the problem occurred after a LONG NO USE period (4-5 years).Take the valve covers off and check all springs , then check when cranking then when running if all looks good.......Hook it up to an external tank of fuel thats half atf take the filters off and dump them out and fill with atf crank that gall and let her eat I think you have some sticking issues in the pump or injectors from this sorry fuel we have nowadays
This is usually an unseated intake valve, could be from an adjustment too tight or a burned valve or seat. Sometimes weak valve springs can do this also.What is the "popping".... it is coming OUT OF THE AIR BREATHER.
