My engine cranks good but doesnt want to rive up or idle, it keeps dyeing out. It had a code to replace the mass air sensor so I did and no help. I took the fuel line off and when I turn on the switch it pumps out some fuel but then stops. Is it supposed to do that or keep pumping? Frank

The fuel pump will deliver fuel as long as you are cranking it over, stop and the fuel stops.

The battery may be bad, they also work with the accessories yet. Must be the best way to test the battery is to have it load tested, which is usually a free service at any auto parts repair shop.

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.
