Talking fuel issues

I've got a stock 90 NA Vert that shut down a block away from home after I made a left turn. I replaced the fuel pump and filter but it still won't start. it's getting spark. I primed the fuel system with the jumper plug and the pump keeps going.
I thought the pump stops after the system is pressurized? After cranking the engine it still doesn't start. The plugs fire but they're not getting fuel. Fuel is getting past the filter but not to the engine. Am I overlooking something?

well if fuel is making it past the filter maybe you have a problem with your injectors? Have you checked your fuel system pressure or the actual fuel pump pressure? the pump should stop after the system is pressurized, so if the pump keeps going it might mean the fuel system isn't holding pressure properly, if there is low pressure the injectors won't be able to deliver the fuel to the engine, hence no start.
