Default No crank no start help reduced engine power

Ok so I’ll start off by saying what all we have replaced it’s my buddies corvette it’s a 98 auto vert car. It has a brand new starter, battery 120rc, ignition switch, I also bypassed the vats the key is #7. We have cleaned and taken the grounds off and cleaned them from all the corrosion. It’s still doing them same thing maybe the resistor for the bypass isn’t working right? Since I bypassed the vats there would be no need for him to buy a new tumbler right?? I’m helping him as much as I can Im no professional so I’m just going off all the research I’ve done and still at this point. Any help would be greatly appreciated
I pulled the codes from the dic
40-BCM NO COMM
60-IPC U1176 H C / U1040 H
80- Radio U1076 H
99-HVAC NO COMM
AO-LDCM NO COMM
A1-RDCM NO COMM
BO-RFA U1096 H U1064 H C
28-TCS C1255H C1276 H U1016 H
10-PCM P1626 H C

You mentioned bypassing the vats. Was it done as noted in the video?

It really doesn't matter where you install the resistor.

Nothing to loose but doing it again at the video's location with the proper OHM resistor.
