It will turn on and turn over but will not start battery is pretty new and starter seems fine just replaced the fuel pump and fuel pressure regulator also no check engine light on drove just fine earlier so just wondering if anyone might have any ideas what the problem might be?

Do you have a check engine light?

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
