Oh my god i need help with my 01 lexus it starts but wont keep running i changed the fule filter and pump also pulled fuses please help

If your think it's fuel related, you already did the hard part, the pump. Remember the pump also runs on a relay that can go on and off until it quits altogether. Also scan for codes even if it doesn't show a check engine light. Something should come up. Hang in there, it will be something simple that makes people get upset. Just be grateful it's not a blown engine. Now that's the real bummer.
