Good morning.
You have a lot of air in the system.
You need a pressure bleeder. Vacuum bleeding or 2 person is not enough to get rid of the air.
You need to put air pressure into the top of the master cylinder and force all the air to the bleeders. You can rent or buy one of these at a parts store.
You also have to bleed the ABS. You will need a scan tool to bleed this unit or you will not have a brake pedal.

The following procedure provides a complete Delco Bosch 5 brake system bleed. The procedure cycles the system valves and runs the pump in order to purge air from the secondary circuits. The secondary circuits are normally closed Off during non-ABS/TCS mode operation and bleeding. Use this procedure when it is suspected that air has been ingested into the secondary circuits, or after BPMV replacement.
The following materials are required:
A Scan Tool
A pressure brake bleeder capable of producing at least 30 psi with suitable adapters and filled with Delco Supreme II brake fluid obtained from a sealed container
A suitable hoist
An unbreakable plastic bleeder bottle to receive the vented brake fluid, with a clear plastic hose sized to fit snugly on the bleeder valves. The hose should protrude into the bottle, with the end submerged in brake fluid.
An assistant to pump the brake pedal
The suitable safety attire, including safety glasses
