No power when I push the gas

When I start the car it idles very high and it runs really rough and eventually dies but when I drive it it has no power when I push the gas pedal but if I just let it idle it goes to 20 mph. I replaced the fuel filter yesterday and it helped it used to just start for 30 seconds then die.

Check for plugged exhaust system, dirty air filter, vacuum leaks, those have a mile of vacuum hoses. Also, check for bad fuel pump.

Sounds like the fuel pump going bad. You will need to check to make sure you have the correct fuel preasure for at least 10 mins. You can find a fuel preasure tester at any auto parts store. Same thing happened in my 2002 Escalade, replaced the fuel pump for around $650.00. Good luck

2004 GMC YUKON DENALI idling rough and trouble starting

unless you want to blow up the intake stop giving it gas before you turn it over what you are doing is dangerous all you are doing is dumping raw unburned gas into the bottom of the intake to the motor, one of these times you go to start it it will do this boom really loud then die, it will lift the whole back end of the vehicle off the ground, then if you try to start it again okay I edited the answer also could be your catalytic convertor plugged is the exhaust coming out good, change the sensors whatever you do stop pumping the gas if it wont start now get in as you need silence so shut the door and the radio off can you hear the fuel pump? it will sound like a huum for a few seconds if you cant there is your problem all I can say is stop pumping the gas as that's why its running bad you are burning out the sensors and all the computer code stuff and wasting expensive gas too. you prolly fouled your plugs as well.
