'90 Grand Prix HEADACHES

Anyone have any knowledge/experience with one of these. Having major
engine wiring probs. I'm not an amateur,and i'm no pro, but i'm ready to burn it!! ANY HELP AT ALL would be hugely appreciated.

scantool says i'm running 40' advance. 6 new injectors, crank senor, intake set. Does mem-cal do anything to timing. seem to be wasting my time in here!! Good help is so hard to find!!
