    I have a 1993 LS400 I got some bad gas and ever since the car won't start.I had the gas tank cleaned and new fuel pump and car won't start. As soon as I crank my car, it shuts off immediately.

Well first run a self test on the computer for trouble codes,l then based on those codes you replace affected parts, but first does it have fuel pressure? how about spark?

My lexus ls400 1991 the two electri fan all time is on

Either the temperature sensor on the radiator, or the relay is bad.
Pull a wire off the temperature sensor on the radiator.
If it stops the fans, then the sensor is bad and the relay ok.

Loss of power on a lexus ls400

the ls400 had problems with the mass air flow meters acting up. You will have to have it tested because they are not cheap. U can get a used one for around 100.00. They cause the car to boog down while trying to accelerate. Check the wires going to the mass air flow to make sure they are making good contact. I have seen this cause a problem. The mass air flow is located on the hose that goes to the throttle body. I have a good one for a 94 to bad you do not live in texas. leave comment
