2002 navigator sputters and acts like it has no fuel
If the check engine light is on have the vehicle scanned for codes. Write them down. Could be in the EGR system or who knows without codes to go off of. Fuel pressure could be an issue and wouldn't throw a specific code. Have the fuel pressure checked for proper fuel pressure.
put a new fuel pump on almost a year ago now going through and changed plugs pcv valve
Like Rowefast suggested check fuel pressure but there is some general maintenance things you can try first like check air filter replace if necessary , clean throttle with throttle body cleaner , replace fuel filter , add fuel injector cleaner to gas tank.
