Check the pcm ground wire on the back of the passenger side head. Give it a good tug and make sure it’s not broken inside the insulation. The other post referred to the frame ground under the drivers door and that one is used by the fuel pump. If you have fuel pressure it’s not your problem. Also is there no ignition power to the coil? Or ground (signal) to the coil?
