1993 Buick Century fuel system

Fuel pump works if I hot wire it at the relay, replaced the relay, no change. Have new 15A fuse and 12 V @ fuse the Voltage drops to 1.4 V when I install the fuse, this is normal. Relay works if I apply voltage to the magnetic coil, if I start car and remove the hot wire the engine stops. I checked all wiring that I could see OK. This problem over night.
What ever you can do for me would be greatly appreciated.
Thank you
Bob
