I have a 2003 Ford F-250 with a 6.0 diesel turbo. The truck never really ran right, it would always bog and sometime kick in real hard. One day I hit the gas and it took off great and ran like I thought it should after I got home it quit running and wont run now. Like it's not getting fuel. I've tried alot of simple stuff like checking fuel pump, filter, etc. Any Ideas on why it wont start now.
