2000 Mercury Grand Marquis Q&A
2000 Mercury Grand Marquis Question: Ran out of gas - added gas to tank and it will not start.
The low fuel level sensor may be stuck on the bottom of the tank. How much fuel did you put in. It should be at least 5 or more gallons. the fuel level sensor can shut down the injection system on many cars, meaning it can shut down the fuel pump so you don't run the fuel pump dry which can ruin it. The fuel is what lubricates the pump. - dandd
I would try to add more fuel like dan said if this does not work i would try replacing the fuel pump relay if this doesn't work i would check the fuel pump, and get a diagnostic to see if they are any codes - sinautoscan.com
