I started my truck this morning and walked away from it to let it warm up and i didn't even get 10 feet away and it stalled. I tried to restart it, but it wouldn't start. I figured it was the fuel filter as i hadn't changed it in a while. So i just got around to changing it now, tried to start it and nothing. It still won't start. Any ideas? I will be calling the dealership tommorow to have it towed in as it is still under warrenty.
