75 2.0, not run in at least 7 years

[NYPorsche]

Going back to the parents next weekend to help with my dad's 2.0 that is finally getting worked on again (bought as a project back in '97, hasn't had much done since then).
At the time of purchase, we were told that the engine ran, barely, and had some fuel issues. The engine has not been touched since then, except for getting removed from the car a few weeks back. The weekend will be spent working on the engine. Whats the best way to go with this? What needs to be done first? Planing on starting with changing the oil and getting some lube in the cyl and seeing if it'll turn over. Then a compression check. Anything else I must do or check right away?

Any advice is appreciated!

Thanks!

I would check that all the fuel lines and vacuum hoses are in good shape and connected properly. I understand that the diagram below is basically correct but you might want to ask Goeff Bleyseng for more details. You might also want to replace the fuel filter and add some fresh gas. Remove the spark-plugs (carefully they tend to strip the threads) and squirt some oil in the cylinders and turn the motor over by hand a few times to make sure nothing is seized. Oh, and check that all the ground straps are tight.

I would change all the FI fuel hose (30psi) with new Porsche high pressure Fuel injection fuel line with the proper clamps.
Fire is a big risk with 30 yr old hose or improper hose ie: regular fuel line for carbs (5 psi)
Injector seals
Clean and polish the FI grounds
new vacuum hoses
new plenum to runners hose
adjust the valves
new exhaust gaskets at the heads

Regarding the fuel lines, make sure you replace the short ones on the injectors as they're usually the first ones to go. You may have to cut off a crimp fitting if they haven't been changed out yet. I hope your metal fuel lines in the tunnel haven't clogged from sitting that long. I bought a 74 2.0 that sat for 5 years and the fuel lines were plugged solid with varnish. The only thing that worked was to put simple green in hose attached to the clogged fuel line, attach the other end to a portable tire compressor, crank up the pressure and let it sit for a coule of weeks until the clog dissolved.
