Yes, that's a 72.

That's not the brain. You can jump start it, but the best thing to do is 
connect the jumper cables and then run the donor car at med RPM for a 
minute or so to get as much charge as you can into the OLD battery. Then 
try to start it. Chances are it won't, since it was probably parked because it 
didn't run, and these things, like moldy cheese in the frige, don't just get 
better when left alone.

You need a Bentley manual to deal with this, and a lot of time to ask 
questions. Start by getting in the car and turn the key ON. You should hear 
a relay click and another click a second later; do you hear both of these

Probably a bad sign, meaning that it was rebuilt and something didn't work 
out and that's why it has been parked.

The FI wires are ALL white.

Plugs are actually easier to change on the FI engines than on the dual carb

Do the test above. With the key ON check that you hear 10 or so clicks from 
the FI injectors as you  press the pedal to the floor. Listen under the front of 
the car to see if you can hear the fuel pump running during that ~1 second 
between the 2 relay clicks.

Maybe tell us where you are so you could get some FI help. This is NOT 
something you can expect to just pick up quickly from an email or 2.
