With the car i'm looking after taking care of, when you start the car, it will turn over fine, start running, then fall flat on it's face. Sounds like what you have. Try starting the car and pumping the gas pedal. When you look at the car, or try and figure out what's wrong. You'd think, starter's bad, bad plugs, wires need to be replaced. But, if you start the car, and go about 3/4 or 1/2 throttle and tap it that far as fast as you can, my(babysiting) car starts and just idles bad for a while. Try it and see if it's working. Another option, is everything grounded out?
