4.7 h.o. problems

[apollo732]

I have a 02 grand overland with a 4.7 it has a hard start problem hot or cold. It will start on the third or fourth crank. I replaced the fuel pump thinking is was losing fuel pressure.. That seemed to help for about two weeks.. Its doing it again, but, my fuel pressure gauge pops right up to "60" psi with key on. and It runs at 66-68 psi?? Every where I check it is supposed to be around 50 psi. I am at wits end with this thing. Any advice before I take it to the dealer?
thanks

I would be looking at fuel lines and connections when running. A very small leak could allow the fuel to flow back into tank when setting and not running, thus you are waiting for full fuel delivery and the air to seep out while you crank 3 or 4 times at start up.
