fuel pump relay, fuel pump, tank screen, not necessarily in that order.

Water in the fuel will drive you nuts, but I'd not add water remover myself, I'd drain the tank instead. Use the water remover AFTER you get all the water out of the tank.

You MUST get the water out of the fuel distributor pronto if you have any in there, else it will rust away and fail, very expensive these days.

Make sure the ignition module is OK, the wires are OK, and the cap and rotor new and sealing -- condesation causes carbon tracking, and failed cap and rotor.
