as Im only seeing 5amps drawn from the pump now its probably unlikely its got a bad earth.

Thats precisely why you could have a low current flow !

A poor earth connection will give a high resistance and cause a low current flow .

I guess you didn't do O level Physics lol[;)]

The 12v+ supply to your fuel pump comes from fuse 34 its a single wire to the pump and the pump is then constantly earthed at the MP1 earth point near the number plate light behind the carpet

Oops your right! e.g. a resistor curcuit with a bulb reduces current and stops the bulb glowing as bright (Current = Volts/Ressistance). Thanks for clearing that up!

But I still think my point is valid.. a fuse protects agains high current (Amps), so if i have a bad earth on the pump there is lots of resistance and the current is going to be low. So how does this cause the fuse to blow?!
