Question about startup

Hey everybody thinking my my fuel pressure regulator is out, but maybe fuel pump, or injectors. My 4.0 has always seemingly started up kind of slow but lately it's gotten worse. I let it cycle with the key on for about 5 seconds and it's still not great. I put a new diehard platitunum battery in a month ago which definitely gives the starter more kick but lately seemed to stop helping much. It idles higher than usual sometimes as well, not sure if it's related, and the gas gauge is sometimes off by a decent amount. Any ideas?
