thank you guys for the responses, i will check it out and get back to you if the car start working properly or not

Hello, i am having an issue with my 2007 subaru impreza hatchback. The car will start normally but die and even pressing the gas pedal it immediately loses power, trembles and dies. I tried changing the gas pump since the old one was not good it still dies. I tried changing spark plugs since the old ones were worn still the same thing. I tried cleanning the MAF sensor and changing the O2 sensor still the same thing. I tried using another throttle body to see if that could be the issue and still it would die. I brought in the car to scan and nothing came up on the scan tool and there is no check engine light on the car. What could be causing this problem?
