Non Starting all of a sudden! pants well and truly browned

As Topic says,
94 Mazda Rx-7 FD Efini(import)
Re-build in 2004, 14,500 miles ago
Recent service at WGT - all reported to be well.
Car was fine in the morning. Parked up, went to start later, and the following happened:
1. Dash illuminated as normal, and engine began to turn
2. Apexi FC screen illuminated, but did not change from the Apexi logo to the temp guage like it normally does after a few secs. It just stays on the logo.
3. On the turn of the key, some bleeping noises were made, then the rev counter began flicking erratically to 3000, rpm, then 4000, down again, etc, it continued to do this flicking even after I stopped turning the engine, and only stopped when ignition was turned fully off.
I am quite mechanically minded, but I do not even know where to start. Presumably the engine is telling me theres a fualt and the bleeps and rev flicking is some sort of engine diagnostic code?
If anyone can help at all, I need calming down
Cheers
Ben

BTW, a solution that worked for me to keep the commander connection tight.....plug it in and run a small bead of silicone caulk around the plug and PFC body. Once it sets-up, it will keep it from coming loose but is easily removed. It also keeps moisture and dirt out.
Understand that this is just an idea. Won't cost anything but time to check and eliminate though.

mine usually comes loose while driving and when it does that my idle goes all over the place and the commander goes back to the loading screen. as for non starting, my nuetral cut-out switch went bad recently. that's another free and simple test. underneath the dash you'll see what looks like a metal box with the clutch pedal arm resting against it. pull the plug out of the back and stick a paperclip in it. if it starts, that sensor is bad so you can either replace it or do like i did and splice the wires

check your crank trigger connections on the front of the engine, they will cause it to not start and make your tach jump erratically.
No idea why the PFC display isn't working though.

Ok I've uncovered the PFC, In my RHD model, it was behind the left hand kick panel, not really secured there just floating about really.
Anyway, clutching at straws, but is that white connection space supposed to have nothing in it?

correct, that's for connecting a laptop. my ecu was unsecured too and that's what always worked the commander plug loose (the large black plug at the forefront of your picture) still doesn't explain why it why it won't start :/
