Is the fuel pump on a Toyota 22 r-e pickup supposed to only run when the starter is cranking?

I have changed the fuel pump and checked that there is fire going into injectors. I have also changed plugs, wires and fuses and it will run when gas is poured into carbuerator but truck still won't start. Any ideas?

First of all, 22RE is fuel injected. 22R is carbed. Which one do you have??? If it is EFI (22RE), the fuel pump will only turn on for a few seconds when the key is turned on, then when you crank it and it starts it will stay running. Keep in mind, the fuel pump will NOT turn on if there is never adequate oil pressure, so also check your oil level.



If it is carbed (22R), the fuel pump only runs when the engine is spinning at any speed because it is run by the motor.



Hope this helps.

No....



The fuel pump runs all the time. It's what transfers fuel to your engine. So if it's off, no fuel is going anywhere.
I mostly agree with nn2004. I would however check the plugs to see if they're getting wet. Did you change the fuel pump yourself? When you turn the key on, you should have a buddy listening for the fuel pump and see if they can hear the pump running for a few seconds. Then it will shut off. You might have left out a step if this isn't happening/
