Multimeter!! What voltage are you getting at the pump with ignition on?? and fuel pump relay number is either 80, 67 or 167 far right of fusebox you should feel it click when switch key on. Check fuse aswell

Was it an 8v k jet or digifant before? Did you change the pump? The 8v Kjet pump will work but if it was a digifant it will be a different setup and it takes it's live from the ecu because of the electronic injection. I think the relays are different too.

it has a 16v fuel pump and it has all the loom out of the 16v the relay is not clicking at all but when i send power to fuse 18 which is the fuel pump fuse it works but other than that nothing happens, every bit of the electrics work in the car other than that , thanks for the help lads, is it the fuel pressure that controls the KR system or the ecu

check the back of the ignition switch, iirc there is one constant power to the switch which should be the middle one, a constant earth then there are two more that come live when 1. the ignition is switched on and 2 when the ignition is cranked. the ignition crank one goes directly to the starter so id imagine that the other one powers the fuel pump and other engine electrics etc. test the switch see what voltages you get at each ignition switch

thanks lads
ya must check the ignition switch , is it the fuel pressure that controls the pump operating so?, if so is it the sensor with two pipes that come from the metering head that dose this
also the car engine runs fine when i put power to the fuse for the fuel punp
