ford bronco 1990 5.8 8 cyl?

I forgot also some of them won`t turn on the fuel pump till it sees oil pressure and then turns the relay on .........safety feature so you burn the engine up in case of oil pressure problem ......could jumper pass oil pressure sender and see if it gets pressure then .....

If you can run fuel pump from relay to in tank pump the problem is between the key switch .computer ..possible a anti theft problem or opem wire in system your proably ona need a schematic of wiring .....
