No power where is relay? for 1984 3.8 fuel pumps

Question edited for a bit more clarity ' carbiator ' :>D You must be Australian.
All questions need 'year make model'. Dawning on me, that you mean 1984 FORD F-250! Ah, and 'Out new fuel pump I' should be 'Put new fuel pump 1'? No one proof reads in America or the Antipodes!
Question moved to correct category.

What is a 'fizgram'?

Check the fuel pump relay for correct operation. If there are two pumps, there should be two relays. You can swap one for the other as an easy test.

Here's a link peter. 1986 Corvette Fuel Pump Relay replace

Its part of the fuel pump in the gas tank

from the fues box under the hood

replace the oil pressure sensor on the engine for the fuel pumps prime comes from the circuit before the relay takes over

IF THE FUEL PUMP YOU REPLACED IS ON THE ENGINE BLOCK IT IS A MECHANICAL PUMP AND THERE IS NO RELAY OR PUMP IN THE TANK. NEED MORE INFO TO CORRECTLY HELP

If it's like mine, the relay is located on the passenger side fender wall. You should see a set of 5 relays together. It is the first one in the back.

have you checked the ground wire to the pump.

Find the fuel pump relay which might be under the drivers side seat its possible its sticking. Also check the fuel pump reset switch should be located in your trunk sometimes these stick open. Its one of the two and I think its the fuel pump relay. Check both.

Check the fuses, I think power to the tank pump is supplied via a fuse. The pump will have power all the time!
