I just put in a new fuel pump and emptied out the gas tank. Put new fuel in and started to drive the truck then it started to bog out like it was loosing power and not getting enough gas, now it will only idle for a minute and engine will shut down. I changed the fuel filter also. I dont know what to do next? What is wrong?

It will only idle for a minute and engine will shut down.

When it does this do below immediately

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
