Low on fuel, battery went down trying to start, added 2.5 gallons of fuel, charged battery still no start. Swapped fuel pump relay, still no start. Getting ready to check all fuses with DMM and fuel pump check point in engine fuse block. Will post some results shortly.

Battery is 12.6v, ECU relay socket is 12v/220mv/12v/0.6mv. Plugged ecu relay back in while key was on (forgot) and heard/felt it click so I'm adding it's good.
