Engine won't start!
 

Hello evryone....I'm Erik,new to this site.If i need to do a formal intro just let me know as this is my first post here!I just bought a 95 GT auto from my buddies girlfriend today,it needs a couple of things but i got it real cheap(500.00)the ignition is messed up because some butthole tried to steal it but that's not the issue right now.He towed it to my house because of the ignition problem that it's causing it to drain the battery and i'm pretty sure that it needs tha tumbler set!He fired it right up with a jump box and it was idling in my driveway for about 20min. and then it died1I think it ran out of gas.....i checked the guage and then added some gas and now i can't get it to start back up!Did the fuel pump loose it's prime or what?I don't know much about Mustangs as i am really into old cars and not up on tecnologly with newer cars!So all of your help will be greatlly appreciated!
