1996 q45 250K fuel pump not turning on

[IDRVQ45]

car stalled and died, would crank and start for a few seconds and progressivly got shorter (staying started ) with each crank. this sent me straight to fuel pump as problem - long story short - based on forum posts i could find - disconnected fuel pump and ran 12v direct and it did turn on - and yes prior to this it did hum ( actually i.ve had the hum for over 150K ) - i never said this wasn't my fault - anyway fuel pump runs ( i will change tho ) removed and checked controller all looks good no burns or overheating marks - based on post i tried the bypass to ground, still fp dead what i noticed however is about 5sec after i turn ignition the relay does click but when i checked voltages when it clicks it removes 12v from the fp ( yellow wire with blue stripe) - any help would be apreciated - thanx
