1998 Chevy Malibu 6 cyl Automatic

I have an issue with my car. We drive it at night runs fine, it sits for 8 hrs. When we go to start it, it turns over but won't start.I then leave it sit for 8 more hours during the afternoon and it starts right up. Then the same thing happens drive it at night let it sit, try to start in morning. Nothing. Let it sit, try it in the afternoon after 8 hours starts. Could this be the pump or something else?

To confirm what's causing it do below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-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
