Why did you cut the cat off?
You need to do some proper testing first.
Check fuel pressure for up to par.
Post back fuel pressure readings key on engine cranking and engine running and the engine running on the road pressure test?
Did you use AC Deco replacement parts and Delphi fuel pump?
Remember Gm engines hate after market off brand stuff.
I have even saw them refuse to start or run with white box stuff!!!!!!!!
