2009 Chevrolet 2500 - Ran rough, then quit

truck started started running rough, shut down, now wont start or even turn over

Sorry to hear that . So what are you going to do besides making a web post ?

Presumably the check engine light came on before the truck died completely. Have it towed someplace you can have the codes read.

Sounds like a fuel supply failure. Check fuel pump. Have someone listen near the gas tank then turn the key to the on (not start) position. A small whirring should be heard for 2 to 3 seconds. If not you have a bad fuel pump or no power going to the fuel pump.
