starting woes
 

My 2006 gmc sierra hd turn off while driving. It Cranks but won't start. The fuel filter was changed 2 months ago and the truck has 77,000 miles. What do i look for?

Check for prime on the fuel filter. Could be fuel filter head needs to be rebuilt. Does it fire at all?? Its possible that you sucked up some bad diesel but you need to check to see if you can get anything at the filter prime.
