2004 Armada won't start

[seven35]

I have a 2004 Armada, I accidently ran up on the embankment and the vehicel cut off. It won't start or if it does it won't accellerate to full throttle. I had to have it towed home. I had someome replace the fuel pump but it still won't crank and run. Any suggestions?

Have you had someone check any stored codes in the computer? If you got to a level enough to make the vehicle think it was about roll over, it may have put the vehicle in limp mode and cut the fuel to prvent a fire. That sounds like that's what happened. I am surprised the airbags didn't go off also.
