Default 99 Blazer 4.3 P0301 and P0102..HELP

This is the Blazer from hell. Working on getting it to pass emissions and it went from no code to these codes repeatedly. Now the junk turns over and over and won't start. I have fought with it for 5 months. After it sits over night it can take anywhere from 1 to 10 times to actually start, but then through the day it starts up easy and normally. Until the last few days since I have been fixing the codes. The sensors are brand new, yet the code still comes back, and now it refuses to start. HELP PLEASE!
