Replaced fuel pump and injectors still will not start unless. You spray starter fluid in the fuel body
Car will not start on its own but will if you spray starter fluid in fuel body. on 2003 Hyundai Elantra
Also try this IF pump is working, unhook throttle position sensor and try it, POSSIBLY stuck in the wide open position and triggering clear flood = NO GAS TO CYLINDERS.

When you're trying to start it ,are ALL intake hoses from the air cleaner to the throttle body connected and no air leaks?
check your fuel pump if has power, change fuel filter? check fuel pressure.
