New car!! Need advice on starting!

Ok I tried to start the car again last night. unsuccesfully.

I couldn't get any gas through the lines from the tank so I ran 8FT of rubber fuel line to a 5 gal can of fresh gas and attached the other end to the fuel pump. She is getting plenty of fuel now when you crank it, but she will only hit when you hold the pedal flat on the floor. She will run for 10-15 seconds but never over 1500 rpm's and if you lift your foot off the floor it will die immediately.

Anyone have any ideas?
