How do you restart buick century 1999 fuel injection after adding gas running out of gas?

After running out of gas in your 1999 Buick Century, you'll likely need to prime the fuel system before it will restart. Here's what to do:

1. Add Gas: Add several gallons of gasoline. Don't just add a tiny bit.

2. Wait: Give the fuel pump a chance to draw fuel from the tank. Wait at least a minute or two, perhaps longer. The longer you wait, the more likely the fuel pump can draw the fuel.

3. Turn the Key (Without Starting): Turn the ignition key to the "ON" position (but don't crank the engine). Listen carefully; you might hear the fuel pump whirring briefly. This is normal and indicates the pump is working. If you don't hear it, this is a potential problem. Do this several times. Allowing the pump to prime is very important.

4. Attempt to Start: Now try starting the car. If it doesn't start immediately, don't crank it continuously. Give it a few seconds to prime before trying again. Repeated cranking without fuel will only damage the starter.

If it still doesn't start after several attempts:

* Check for other issues: Running out of gas sometimes uncovers other pre-existing problems. Make sure the battery is charged. Check all fuses, especially those related to the fuel system (your owner's manual can help with this).

* Consider professional help: If you've followed these steps and the car still won't start, it's time to call a mechanic or roadside assistance. There may be a more serious problem beyond simply running out of gas.

Important Note: Repeatedly cranking the engine without fuel can damage the starter motor. Be patient and let the fuel pump do its work.
