No bus, no power to fuel pump

My '99 Breeze will not start. I am getting a "no bus" signal on the odometer and the fuel pump is not powering up when I turn on the key. I changed the fuel pump but still no power. I had a couple of camshaft codes (P1391 and P0340) when I went to smog it. Today I changed both crank and cam sensors and still no power to the fuel pump. I tried using starter fluid just to see if I was able to make it run for a sec but it seems no spark is getting to engine either.

When I ran a scan tool, no codes were detected.
