No they will not if the code number was po171 have your fuel pressure checked it should be 55 -60 psi to start your car if it is po171 this is a lean code that a weak fuel pump will cause this code not a o2 :)
An o2 sensor code will very rarly be related to a no start condition.I am a chevy technician, The most common problems on these vehicles is the fuel pump which is located in the fuel tank. Check fuel pressure.
Ignition control module a bad fuel pump could have leaned out truck causing o2 codes before pump quit hit the center of bottom of gas tank if it starts it definatelty needs a pump but have someone turn key while you are under vehicle see if you hear pump
