2004 Duramax Engine Light On
 

Had my 2004 Duramax checked at Autozone for trouble code.
They came up with P1093 but didn't know what its for.
Checked on this site and it said fuel rail pressure low during power enrichment.
Do I need to change my fuel filter to correct this problem or is it more serious?
Thanks! John

the 1093 if often related to a restrictive fuel filter.
