Now that we have collected some good DATA on the SYMPTOMS of the Crazy Ghost living inside this 2004 Toyota Avalon, we have to look at Wiring Diagrams and see how in the world these issues could possibly be tied together:

-Stall/stumble on Cold Start
-Clicking Fuel Pump Relay
-Flashing/flickering Check Engine Light and Low Fuel Light
-Transmission Solenoid Code
-Flashing Info Display
-Wonky Temperature Gauge

Can we nail down the root cause with ONE scope measurement, and maybe fix it No Parts Required?
Or is the WEIRD Toyota hiding more tricks up its sleeve?
