Question about 1992 Lexus Sc 300
Vehicle: 1992 Lexus SC300 - Blowing smoke out tailpipes,white to light grey, smell of fuel somewhat strong. Fuel pump will not shut off when ignition is on, but engine not running,could this be a pressure regulator issue ? To get engine to start I have to press the gas pedal so it will not lock up, like a "hydro lock" problem. I am sure,but not certain, it is not a head gasket due to water level staying full. Engine has very rough idle and driveability ,even after full tune up, cap,rotor,plugs,wires,fuel filter. Check engine light is not on,and does not come on while the car is running. O2 sensors & alternator have been changed recently also.
