Figured it out... well kind of. First off, online has nothing for these buicks. Found everything through envoy. Found wiring diagram for injectors. Had power at the fuse no power at injector started tracing wires. Un plugged the main harness by the fuse box. ( not sure if my wires ran through it) found my power wire right before it splits into 4 and goes to the injectors. Stripped it back had volts there. Checked again at injector had it there. Everything works. Put it all back together gave it a tail light warranty and hope to not see it again.
