Default Help please

I have a 2007 Cadillac sts. I started to have misfire and car had no power. Changed coil pack on the cylinder misfire. Misfire is worse now. It started out blowing up coil packs. Now I've changed PCM, complete wiring harness. Now the 1 3 and 5 fuse is melting. I'm at a loss as what to do.. Any ideas? Checking engine light is flashing. Its a constant misfire..

Not that way, If fuse is melting is like low amp short, possibly a chaffed wire. Connector 120 appears to be multi wire connector at rear of engine common denominator of your troubles check condition an harness routing. Has timing chain been checked for excessive wear? V6 has some chain issues leading to misfires
