Where is the fuel emergancy shut of valve in a lexus 91 Ls 400


Toyota products usually don't use a shut-off for the fuel system.
If the fuel pressure is low, you would need to check the fuel pump relay for power and then the pump.

Where is the alternator located on a 1991 ls 400


The main purpose on an alternator is to recharge current back to the battery. One of the most common problems with the Lexus LS400 and SC400 is that power steering pump seal leak. Right below the power steering pump is the alternator. The power steering fluid will drip down and cause many electrical problems for the alternator. Therefore, its very common to have the alternator go bad along with the power steering pump, just be sure to check.awcforever.gif

Sc400 has lost acceleration!!!!


A simple loss of power could be contributed to several different things without knowing the exact symptoms. Throttle position sensor, a slipping transmission, faulty coil pack(s) or fuel pump can all cause power loss. Is it intermittent? constant? does the car run smoothly and just experience power loss or does it run rough? The more information provided the better I may be able to help.
