bad contact on ign switch maybe ? at a guess I would say ign energises the relay that supplys live to pump, or bad wiring somewhere.

what if i changed the loom from the fuel pump to the one under the car by rear axle? do you think that might help??

Dodgy bit of wiring somewhere, only thing it can be besides a bad earth on the pump, but seeing as you can put a live to it and then it works....

hi, right i will try keep this as simple as possible.... a few weeks ago my car wouldnt start, i ran the battery dead trying to start it, tried bumping it/jump starting it, and still nothing, anyway after much confusion, i finally narrowed it down to the fuel pump not priming, i put a live onto the pump and it fired first time.
now, every so often (once a weekor so), it does it wont start because the fuel pump wont prime and it takes that little buzz of power onto the pump to start.
i have changed the fuel pump, changed the relay, and checked all fuses, and even crank sensor, but still i cant find a cure. SOMEONE PLEASE HELP ME :(

thanks
