alright, my tour is still not 100%, still kinda lookin for a few words of wisdom

we pulled codes and got O2 sensors and insufficient EGR flow codes. we replaced both O2s and were gonna clean/replace the EGR valve, but it was driving fine (or so it seemed). drove it locally for most of one day, but then I went to start it again and it wouldn't start. it cranks, but wont turn over.

my question, could a clogged/old EGR cause this? symptoms are mostly stalling/not turning back on, and it's the only other CEL we're getting. I think we're replacing it regardless, but I don't want to go driving it again if this could in no way be the cause of my problems.
