Hold on dude, take a deep breath, walk away from the car and take a time out.
Sometimes I lose it when the problem is electrical too. This elect stuff ain't easy, but some small diagnostic steps will get you results!!
This system is more complicated than you think.
1. Do you have any computer codes in the computer?
Page FL-26 Service Manual
2. First off, fuel line 'pressure up" is controlled by at Vacuum Switching Valve (VSV) which inputs to the ECU...... Page 53 Elect Manual, Page FL-3 Service Manual
a. Without this input your electrically connected but there is no pressure in the fuel line.
b. (Toyota uses this to kill extry line pressure when you get off the throttle.)
3. The circuit opening relay attached near the ECU controls the power going to the fuel pump....see Page FL-111 to diagnose this relay.
4. Since you already checked the AFM then you unknowingly may have checked the Fuel Pump Switch inside the AFM. (you checked the Fc input)
Yes, it's not that easy but this is how it's done.
