Check all of your fuses.

When you powered the pump directly, where did you tap the power from? You could also have a harness issue.

If that's the case, it might be something in the ECU, or a sensor, both of which are very hard to diagnose for sure. You might have to find a similar bike and plug in that ecu. Small chance your spark plugs are fouled...

hi thanks again for getting back to me the first thing i did was change the plugs and put a new fuel pump on as the old one was rusty cleaned all the electical connections and checked the wiring with a multimetre and did not find any breaks i was told yesterday there is somthing to do with a power command or somthing like that iam going to take the tank of again and double check the wiring and for a spark, but i do think its the ecu/cdi thats the problem so see what i can find regards mike

Hm, if there is a power commander or anything aftermarket installed, get rid of that and try to get it running bone stock.
