Doing a 82 SWB Sliverodo. Motor is a LS6 out of a ZO6 2001 vet. Transmision is a 4L80e. I’ve got 12v and ground ran to the battery small red wire to 12v Constant red and white wire to keyed 12v. Black wire to a good clean ground. Each coil harness to back side of the heads. Coils are firing. Fuel pump will not come on. It was coming on yesterday but only when you first turned the key on but not when cracking. Today it want come on at all. No power from the pump wire green wire. What am I missing here? I’ve uploaded two different base tunes no help.
