I have not had same with any of my lexus, but when the ECU failed on my Bosch D-Jet 914 2.0, it did exactly as you describe. so much fuel that it would leak out of the exhaust (dripping) and fill the garage with fuel vapor (no fire hazard there!!). Any way to source a known good ECU, to make a check?? That is how my car was dignosed in the end. Perhaps the local dealer would have access to another ECU, CL members?? CL Classifieds (even a SC 300 ECU, Any 2JZ, should work as a quick check. Have heard of some Fuel Pump ECU issues, but they seem more related to too little fuel, so that leads me back towards the Engine ECU. Best Luck! - Brent.
