check your air flow sensors or get it to an autozone to pull codes but it like its getting too much air and not enough gas

Is there a check engine light on? Can you get it somewhere or do uou have access to equipment to have the codes pulled?
Have you ever replaced the O2 sensors? Might be the issue. Running too lean.
Air, Fuel, Spark, check first. Apparently there is spark because it runs for a while when you pour gas down the throat. Does it have throttle body? First I would check the fuel pressure. If good pressure, then I would check delivery of the fuel; your injectors. According to pictures of your engine bay online you have a throttle body injection. You can see the injectors pulse fuel when running with the air cleaner off. If no fuel then maybe a clogged fuel filter or bad new fuel pump or fuel pump relay. No power to fuel pump. Relay is to the left side under the plastic cover (passenger side) engine bay at the firewall. It really sounds like fuel delivery. Hope this helps.
