Hello aaron,
Drain the fuel tank and clean the drain screen by removing the plug in the bottom of the tank. In addition you can do a visual inspection of the inside of the fuel tank, by removing the fuel gauge sending unit in the trunk under the rubber mat. Caution, gas fumes can ignite.
Next remove the main fuel filter canister and replace the main fuel filter. It is the aluminum canister which is mounted on the left front engine support. If the fuel system is really dirty you may need to remove the intake fitting on the electric fuel pump (under the car) and clean it also.
Add fresh fuel and turn on the ignition. You should hear the electric fuel pump run (under the car).
If the electric fuel pump runs but you have engine running problems, there are two items on the mechanical fuel injection pump which can get stuck from long periods of inactivity. The Warm Running Device (WRD), regulates air/fuel mixture during engine warm up. The "rack" in the injection pump can also get stuck in severe instances. I suggest you search up and read the "injection pump tour" to familiarize yourself with these problems if needed.
Welcome to the group, keep us up to date!
