good afternoon my name is ***** ***** I will assist

the first thing I would do is check the fuel pressure. it needs to be checked with a gauge. just pushing the valve says there is some fuel but it needs a specific amount of pressure to run. it does sound like you need a fuel pump. you can rent a tester at a parts store to verify the pressure

No it does not run with starter fluid . It acts like it wants to start but it doesn't
