I have a 94 LS400 that have been running great. No problem with starting nor while driving. Last Thursday, it would not start.(starter cranked, engine turned but will not start) Assuming it's flooded or not enough gas, I removed the key, waited for about 20sec, tried again and it started right up. It happenedone more time onFridaybut ran fine thru the weekend. Monday morning I drove 20miles to work with no problem. At lunch, while driving the engine quit on me.I pulled over, waited for a little bit and it started back up again. Today on my way home, it quit on me again except this time it will not start back up. Any idea/fix or advise will be most appreciated. Thanks for your time.

 

Take your car to the nearest Lexus dealership or to a Lexus authorized garage that can extract the OBD codes from the ECU.
