When I bought the jeep it started right away and now I have to turn it on wait for the fuel pump to run shut it off press the gas and than it will start. I know it is not the fuel pump because I had that checked. I think it might be the fuel pump or the injectors but I do not know what one to go after first
Have the fuel pressure checked and make sure it is up to spec. If you have an external fuel filter you should replace it before getting it tested. You can borrow the test tool to do this at Advance Auto or Auto Zone.
