All that fuel has gone to your cats when it would not run. I'm thinking your cats are clogged up. Plugs got fouled gradually or an O2 sensor went bad so the fuel was not burned properly and it got dumped to your cats, they got clogged up. Or an O2 sensor went bad and that clogged up the cats. I had that happen on an Integra many moons ago, the extra fuel actually ate through the cats and turned them into straight pipes. It failed inspection, but not by much…took it to MIdas and they showed me what it looked like when they took it off.
