After a quick browse of the Vortech manual I assume you checked the MAF and TPS connections and vacuum leaks?
So MAF is installed but I think you could still fire up the car with the MAF disconnected it would just run funny. It only goes in one way to the pipe as well.

What is TPS?

Vacuum leak, where do I look for this. The pipe going from the BOV to the throttle body? Everything looks to be attached.

With the Vortech install, do you have to remove the car injectors and fuel rails? I assume so. Mine are all mounted to the bottom half of the Whipple supercharger. Sounds like maybe you need to let the fuel system pressurize. What's the fuel pressure at the rail for the injectors? Did you unplug and relays or fuses for the fuel system? When I did compression checks, I removed the fuse for the fuel system.
I didn't take out the fuse for fuel system but good suggestion. I can smell petrol out back. I've tried about twenty times to fire it up. Would that pressurise it?

Bingo. Should be hooked to the throttle body. Upon first power up, turn on the ignition but don't start it. Let the computer look at where everything is and then it will learn where the throttle is at before starting. If it fires up, let it do its thing before manipulating the throttle.

Fitted some Eibach camber bolts and took half a degree off the fronts as it was ripping tyres. Proper alignment as soon as I can, new Contis on Tuesday

Yeah, should be a line from the brake booster to the intake/throttle body area.

Reading through the install I see a new MAF sensor housing gets installed and the MAF sensor moved there. I also see the fuel boost pump gets installed and a connection in the driver's side (America style) rear seat kick panel gets disconnected. Lots of vacuum line stuff gets modded too from the looks of things. I don't know why you're smelling fuel. Do you have a fuel connection not mated properly and it's leaking or sucking air? Just trying to help. On the Whipple there's a fuel line jumper that gets installed to route fuel from the left to right fuel rail behind the intake. The plugs to the pressure sensors should be close by there too.

Do you have to climb through the window to get in the car?
It’s a combination of going thru window and sliding out thru the door…..it helps to be super skinny😂

When I sold my Gran Torino sport I did the transport guy a favor and drove it into the eight car enclosed hauler. I had to climb out the window onto a small ladder next to a really, really greased jack screw. Felt like I was at Long Pond again but older and heavier.
