I think i ran my mustang gt out of gas,i just got this car today from a good friend.It was idling in the drive way and then died without warning so i think it ran out of gas according to the guage!I put gas in it but it will not start up......did the fuel pump loose it's prime or?...please help!

You need to make sure you put in AT LEAST 2 gallons of gas, more if the car is not level. It might take a few cycles of the key to get the fuel line primed again. A full cycle is Off-On-Start. When you turn the key to on, listen for the fuel pump. It should run for a few seconds and then shut off, turn the key to start for a few seconds and then back to off... This will have to be repeated several times. You should be able to hear the fuel pump from the drivers seat. I will be a faint hum or hiss coming from the back seats.
