He offered to fix it but I declined and just followed the miles.

I have a 99, SR-5 and had the same thing happen twice. Startup, gauge on full, wait couple of seconds, gauge crashes to below empty, gas warning light starts to blink. Argggh.
I saw an old post that showed a burned out component on a board on their cluster that was blinking the gas light. The component is on the board behind the small white cover on the back of the cluster. Just unscrew the screws, take of the cover, unscrew the small circuit board and disconnect the ribbons and one small wiring connector on that small board. Behind the small board (on the main board) is an inductor labeled “L9”. Since it literally failed and smoked for the guy in the old post…..I decided to check continuity across that component. It had no continuity and had failed (no physical signs of failure though). One side of L9 leads directly to a pin on one of the cluster’s connectors. So I soldered in a 1 ohm resistor (didn’t have any inductors) bridging out the bad “L9” inductor. It worked fine after that.
I think that component pulls higher current when the resistance of the gas float drops/or the sender goes bad. I changed out a fuel pump and it even smoked the new resistors…did the repair again and no issues. For some reason when the gauge starts acting up, that component fails due to high current.
