Shower Pump working overtime

Sounds like the switch (which turns on the motor when water is flowing and off when it stops) has somehow jammed. First thing to do is to turn off the power to it (doesn't sound like you have yet).
I would guess that the reason it was turning on when flushing your toilet is because the pump does not have its own hot and cold feeds but has instead been fitted to the existing hot and cold pipes. Flushing the toilet causes a slight pressure drop in the cold feed pipe, the motor comes on.
If you know which brand of pump you have, contact their technical support line and see if you can get a new pressure switch. If not, you might need a new pump.

make and model would be wonderfull 
Yes, switch is definitely cheaper than a new pump!
As has been said, make and model are useful. Spares should be available at all good plumbers' merchants, although most likely they will need to order them in.
Another question: Is your shower mounted BELOW the COLD water tank, or is the cold water tank on a similar level (e.g. if this bathroom is in a loft conversion)? (just in case: I'm thinking it might be something to do with a negative head kit, although I should point out I am not a plumber)
At least you can run your pump manually for the time being, I would hate to be without my shower pump for any length of time
