Default start up after 2+ years...

As the thread title says, it's been 2+ years since I started the old gal up. I seem to remember a couple different methods for ensuring the oil pump is primed and wanted to verify with the collective here - cranking without the DME relay and/or pressurizing through the dipstick tube. First seems straightforward, as long as the battery holds up (it's being charged overnight). Could someone point me to the thread or article on pressurizing through the dipstick tube? And if there are other options I'm all ears.

Really looking forward to getting her smogged and then back on the road again. Thanks!

Other methods of getting oil primed is taking off the oil filter and pouring oil in the center hole. The fastest way is to pull DME relay and fuel pump fuse. Crank until you have pressure. I tried the air down dipstick method but i burst the air, cause I didn't have a regulator. I think it's 15 psi. Any more you'll risk the oil pan gasket. I'd replace fuel filter while your at and drain bad gas out. And run fuel injector cleaner after getting her started.

Pressurizing through the dipstick tube? That is not a good idea as the crankcase would be pressurized with air, which would likely not provide additional pressure to the liquid engine oil circuit, and it could also potentially cause more problems than it would solve (blowing seals out, etc).

If the battery is strong, remove the DME relay and crank the engine (in 20 second increments or less to avoid overheating the starter) until oil pressure builds on the factory gauge.

i also pull the wire between distributor and coil to ensure no wayward spark.

pouring oil down the filter hole is a pretty good idea. remember the "outside" concentric hole is from the pump, "inside" hole goes on to the rest of the engine.

i just did an engine-out HG and reseal on my Subaru and pre-oiled everything by getting a hose barb fitting in place of the oil pressure sender and hooking up to a handheld fluid transfer pump with the "feed" hose in a jug of oil.

once the oil gets into the passageways and starts finding restrictions the pumping gets much more difficult, just push thru it. i was able to hand-pump a full QT into the engine this way. the pump was $16 at Oreilly.

Obviously you're going to pull the plugs and check them as well right? And changing the oil before hand? Would be easy to get things primed by cranking with out the plugs in. Check to make sure the plugs are intact and no parts have came lose and left behind in the cyl. I'd prob put a tiny bit of oil in each cyl as well before cranking. Then once everything is primed put (new) plugs back in and fire it up. And of course as mentioned make sure you're firing the injectors as part of the prime stage.

My question to you would be at what point would the gasoline expire and go bad . I'm in the same situation as OP

I don't think age of gas is that big of deal if it's only been a couple years. Our tanks aren't metal. I did an engine swap on my Audi S4 and it didn't run from 2010 till 2015. Very little gas in the tank when I went to start it for the first time. I threw in a few gal and burn it all up. Obviously you prob don't want to go out and hit max boost right away. Prob be a good idea to change fuel filter. (The audi got a new fuel line and filter as part of the project).

Just fill the tank full of new fuel...drop in a bottle of octane boost if so inclined and drive around until you use up the first tank of fuel then good to go. I park my car every fall and pull it out in the spring. Done that every year since 1993
