Check for very small leak between pump and fuel tank that may be sucking air, even if it is too small to leak fuel.

fuel starvation ie blocked filter /blocked pipe / as no fuel is reaching the cylinders
BUT FUEL IN INTACE AND STARTS BUT WONT RUN THIS IS BECAUSE THE FUEL BURNS AND STARTS THE ENGINE THEN STALLS AS NO FUEL CHECK ALL FUEL FILTERS AND FUEL LINE FIRST CHEAPEST OPTION

CHECK YOUR FLOATER FOR LOSSE CONECTION ON THE SOCKETS OR FLOATER HSA LEFT THE LEVER

on an old pump when you run out of gas alot of times the pump fails. If you can start the car with ether then the pump most likley will need to be replaced. .

have the computer analized for free at Auto Zone.. they will advise you what is bad

check to see if gas is making it to the engine, may have bad fuel pump start there,good luck.

Check the fuel pump relay. Check for power at fuel pump keep in mind that negative is used inside the tank.

Your fuel filter is probably clogged

4 years is a problem try empting the gas tank. and put the supreme gas in it on a full tank. check the coolent fluid and if problem still exsist check the fan

have the converter checked out,,,if its clogged it wont allow the car to run right and youll have no power
