Sounds like a fuel problem..... with some cars there is something that cuts gas to the intake when the engine is not running.
It also guts gas if it loses 12v to the device.
What would do that on your car?
Have you loosened the fuel line fitting under the hood,
bled out the air and checked to see how far the gas spits out?-Bob
