So, after fixing a bunch of problems today I managed to get the 2+2 started, first thing was the only air flow meter I could find had been sitting outside for over a year so after pulling it apart and cleaning and lubing it I managed to free it up.
I found a key in the centre console but it was basically solid rust, I tried it in the ignition and it wouldn't turn, I had a spare column sitting outside so I pulled the ignition switch off it which you can turn with a screwdriver and plugged that into the 2+2.
Next was the fuel pump wasn't working, the wiring was getting quite hot and also the pump itself was getting hot, I was going to take the pump out of the white car but thought I'd disassemble the original pump, so I did that and managed to free it up so I put it back in.
Pressurised the fuel system and fuel started to piss out of a rust hole in the fuel filter, so I borrowed the new one that I put in the white car. Tried to start it and it fired right up, ran pretty rough for a while but then cleared up (mostly). The water pump wouldn't turn so I pulled that off, picture below, think I might replace it.
