Just because parts are new doesn't guarantee that they're good. Recheck fuel pressure and leakdown, this thread tells you how to check it: https://blazerforum.com/forum/showthread.php?t=45941
If it's OK, the Idle Air Controller, (IAC) might need to be reset with a capable scan tool.

Always a good idea to replace the gaskets and O rings when removing the plenum along with using the correct tightening sequence and torque specs. Disconnecting the battery will not reset the IAC. It requires a bidirectional scan tool to access the IAC reset function.
