The right turn signal will only work if its hit manually instead of just being turned on once. I have checked the fuses and changed the bulbs, all are good. I even cleaned the connection to the light but have had no luck getting it to flash intermittently once I have turnedd the signal on.

98 buick regal has a strong gas smell

Do you know what fuel pressure regulator is ? These like to leak when they get older !
The cartridge type fuel pressure regulator (1) is a diaphragm-operated relief valve (6) with fuel pump pressure on one side, and regulator spring (2) pressure, and intake manifold vacuum on the other side. The regulators function is to maintain a constant fuel pressure across the injectors at all times. The pressure regulator compensates for engine load by increasing fuel pressure as engine vacuum drops.
The cartridge regulator is serviced as a separate component. When servicing the fuel pressure regulator, insure that the O-ring backup, (3) large O-ring, (4) filter screen, (5) and small O-ring (7) are properly placed on the pressure regulator.
It's located on the fuel injector fuel rail !

I have a 1999 Buick Regal ls car run out of gas

A couple of possibilities. 1st, check to see that the fuel pump is working. When you turn the key to on position (not all the way to crank the engine over), can you hear the pump? You should hear a humming sound from the gas tank . The fuel in the tank actually keeps the fuel pump from overheating. It is possible the pump is shot. It would be a good idea to change the fuel filter, as it may be plugged up from sediment from the bottom of the tank.
