My braking system once it
I suspect you have a caliper dragging. This will cause the rotor to overheat and expand, locking up the brakes until it cools down. You could also have a warped rotor that is heating up and getting stuck on the brake pad - either way I would suspect the caliper ( s ) . You can check them by trying to spin the wheels 1 at a time with vehicle raised and brakes warm. If a caliper is dragging and you have a warped rotor, that wheel won't spin smoothly or at all. Another indication would be a pulling to 1 side or the other when brakes are warm. You could actually have a dragging caliper AND a warped rotor. I would start there and to the test to see if this is the problem.
Good luck!

A green light came on "ECT PWR", what does that

Basically in the older models there is an option to turn ECT on which
allows for better acceleration as it's controlled electronically.
Hope help with this.

It does sound like the sensor is either dirty inside the tank or bad. You will have to remove the overflow tank and the sensor is torward the bottom of the tank and easily replaced.
Where is the starter located
More often than not, the starter will be located on the under side of the motor on the same side as the battery.
trace the red or positive battery cable and it will lead you right to
it. It will be short approx. 8 inches long and about the same diameter
as a Mayonnaise jar.
Having problem bleeding brakes cant find the brake
The bleeder screw is in the back next to the brake line into the caliper. Start the bleeding at the right rear, farthest from the reservoir. Then move towards the front left. Keep checking the fluid level and make sure you don't let go of the pedal with the screw loose. Get a 6 point box wrench on there , about 8mm, and a piece of hose to run the fluid into an empty can. Check it out, hope this helps.
1994 Lexus LS400 has intermittent no spark.
Hi! Have you checked the distributor rotor? This may cause a no spark too. If its good then the last resort is replacing the engine control module or the engine control unit. Hope this helps and have a good one!
Does the 1990 Lexus LS400 master cylinder come
traction control is a separate system. If traction control or ABS is a problem they are taken out of the loop and the normal brakes still work. The master is for the brake system/ The ABS module and valve body and wheel sensors are your traction/antiskip system.
How do i recharge the air conditioner
This is best handled by a shop which specializes in AC repair. I doubt you have the proper equipment to flush, lubricate and recharge the system. It isn't as easy as it once was when you screwed a can of refrigerant to the nipple on the low pressure side of the circuit.
