I have a 2004 Ford f250 6.0l. I was driving it yesterday and it suddenly shut off while cruising through an intersection and I was able to coast into a parking lot. Now it wont start. It cranks, all fuses are good, fuel pump turns on, fuel is getting to the motor, egr was taken out and sprayed down with WD-40, and the only codes it is throughing is one for the egr having insignificant flow and one suggesting an exhaust leak. Could one of those seriously be causing the issue? It seems like there would have to be something more serious than that to shut a truck down while driving. I am no mechanic so I could be dead wrong tho. Any ideas from you guys?
