Might be a fuel issue. Check the fuel pump fuse as well as the relay. Then check if the pump is getting power if the fuse and relay are good.

Crew_Chief, what’s the easiest way to check if the fuel pump is getting power?

You can check the fuse box where the fuel pump fuse goes, check the terminals where the relay plugs in, or you can find the power wire going to the fuel pump and check to see if that has electricity flowing to it. If all of these are in working condition, you may have a bad fuel pump.
