Default Fuel Pump and Relay ( SOLVED)

The fuel pump on my 88 quit, got another pump. I did thejumper wiretest on the fuel pump relay. The old pump doesn't work, the new pump works.

My problem is when I remove the jumper wire on the relay, the new pump won't work. So I got another good relay, still the pump will only work with the jumper wire. I have the Haynes manual but its a lost cause.

The manual mentions a sub fuse??? Any suggestions what to do next??

Pump works better when its primed !! Put the new pump back on the bike, filled the lines with fuel, took a few minutes for the carbs to refill andthe pump works great.
