The traction lock light flashes on the dash panel on my 1993 Lexus LS 400 and the engine shuts off. It will crank up immediately after shutting off at times and some times it won't.

Very possible that the pump vapor locked itself. Had a 94 Lexus that done the same thing.

Can be several things. Fuel pressure, ignition, or sensor related.

Do you have a check engine light on?

Is your check engine light coming on? Sounds as if something is getting hot and then cooling down my research points to a known fault of your year and type of vehicle The electronic control module has capacitors in it that are sub grade and they melt down after awhile and have been known to cause this as well as a bunch of other driveability issues. Replace your ECM and let me know

You need to have someone scan the computer for trouble codes. Most auto parts stores in the US will do this for free in hopes of selling you some parts. The traction control uses the engine to maintain the stability of the car, so you may or may not have a second problem with that system.

try locking and unlocking the doors with the key and make sure all the doors are shut all the way. something is triggering the security system.

There should be defect with sensors. check with engine scanner

The wheel speed sensor may be bad in one or more of the wheels or the traction control module is bad.

Either way, the traction control will not work intermittently.

Have the computer scanned for codes on the traction control side.

the track off light will come everytime yhe check engine light comes on. this is normal. you need to have the check engine light checked first.you can go to your local parts house they will scan it for so you at least see what area you problem is in and then you can start from there. let me know lf you find out youe engine codes.

Clean, inspect and, or, Replace your crank sensor or, crank sensor wiring A loose crank sensor bracket or, a start relay has caused this before

seperate problems. you starter is under intake manifold and is most likly the problem and the dash lights go bad on older lexus ls400's.would have to be replaced.
