172 Cup won't start

[RetroTed]

Hi Guy's

I'm sure this has been done to death but my cup won't start this morning. She cranks but won't fire. There's no power to the pump and the red light is solid

Cleaned all of the relay's and noticed a thin red wire going under the relay box which seems temprimental as when you wiggle it it makes the black box on the inlet manifold buzz. Either way it still doesn't start

Car drove fine yesterday

Any ideas pls

Fuel pump relay in fuse box under bonnet on drivers side?

Is the Earth on the back of the gearbox still connected? It's under air box. Mine worked itself loose and it stopped the car from running.
