I have the same year endeavor with the 5.9 cummins.
Recently mine started acting up as well. Doesn't want to start. You can crank and crank, never starts. If you bump the starter that should get the fuel pump turned on and pressure built so you can start it. If your pump is not putting out the pressure it should, it may take several tries before it starts. That's what mine is doing.
I don't know if mine has the original lift pump, but the previous owner already had a lift pump die and take out the very expensive VP44 pump.
I am going to upgrade my lift pump to something from FASS when I have a few extra dollars. From all the reading I have done, the factory lift pumps are not that great.
