Sounds like you have a fair bit infront of you before even worrying about firing it.
Id be looking to get the car to a state where you have done everything you think you need to in order for the car to fire.
Then pull all the fuel Fuses, and disconnect all spark plugs. Take your oil feed to the turbo off and place in a pot. Crank till you get oil out the turbo feed.
Re-assemble oil feed.
then crank again and make sure you are getting good oil at the top of your engine and its draining from the turbo (and not leaking)
Check the ECU is seeing good feeds from cam, crank sensors.
Not sure about the Link but on the Syvecs you could do coil tests and go through each spark plug to ensure it sparks. (assuming you are not dizzy)
Put fuel fuses back in and ensure getting fuel to your rail.
Can do all of that before even thinking of hot fire
