89 ranger all of a sudden not getting gas

[tototjo]

Hello I have an 89 ranger with the 2.9 5 speed and just the other day it is not getting any gas. It ran just fine then went to start it then wouldnt catch. It turns over and starts when we put gas into the air intake but doesnt get any gas. I just replaced the fuel and eec relays and still nothing. My check engine light doenst turn on anymore since i replaced them and it did before. it has gas i put in a gallon and it wasnt completely out when it wouldnt start. is it the pump? anything else i should do before i go and take the bed off and replace the pump. checked inertia switch and its good. will a pump just go out all of a sudden like that? any help is appreciated. thanks.

Yes, pump is an electric motor and can just not start one day, it usually won't fail while it is running, just won't start again

Ford's computers are programmed to turn on Fuel Pump for 2 seconds when key is turned on, only 2 seconds, but every time key is turn on from off.
Fuel pump is not quiet, you can hear it hum in the cab, so cycle key off and on to see if pump is starting

Also put volt meter/test light on inertia switch and turn on the key, you should see 12volts for 2 seconds if other things are good.

If you can hear the pump run, then it could be Fuel Pressure regulator is stuck open, it is on the fuel rail, Return fuel hose is attached to it.
