Default Does es300 1992 has inmobilizer?

hello. just bought a es300 1992 manual trans. it doesnt start so im trying to diagnose that.
so my first question is, is it supposed to have a key with inmobilizer chip?
it cranks but no start. tried to read the obd1 codes but the cel just flashes fast (no codes).
thank you.

I highly doubt it. Toyotas didn't have immobilizer till 2000.

Time to do some old school diagnostics:

Check for spark at plugs. Remove plug and check for spark while cranking.
Check for fuel at throttle body. Does Exhaust smell of unburnt fuel or spray some carb cleaner into the throtte body.

Hey, Wifey is from Ecuador . Now I have to help you

hey Draco thats great. which part of Ecuador is your wife from? saturday im going to travel to los angeles to buy some lexus parts (here in Guayaquil you wont find any).
i took the car to a shop and they told me the culprit is the MAF (bad readings or something) but the weird thing is no codes present.

I think Guayaquil too, the coast, right?

Hey I am in LA too :-). Yeah, I heard it is pretty tough now with all the restrictions on imports. I guess your prez wants to be like Cuba? :-/

MAF, really? Well, it could be but Let's do some diagnostic first. If you want to.

Okay,

Let's do the easy stuff first.

Do you have a digital volt meter? If so please check the voltage. We need to make sure your spark is bright enough to ignite the fuel. We want to see 12.5-6 volts at the battery.

Check the connectors are nice and clean. Is not loose. Use Lemon Lime Soda to clean connectors

From there we need to check your Spark Plugs for a SPARK. Pull the plug and put a screw driver in it. Put the metal part next to a good ground point to see if you get a arch of a spark while someone turns the key.

Please post your findings

1992 diagnostics are pretty easy,

from this site: http://www.troublecodes.net/toyota/

NOTE: Not all trouble codes will activate MIL (CHECK ENGINE light)
Before proceeding, make sure the:
CHECK ENGINE light circuit is functional. It should be ON when the ignition switch is ON with the engine stopped.
Battery voltage is above 11 volts.
Throttle valve is fully closed (Throttle Position Sensor IDL points closed).
Accessory switches (A/C, etc.) are OFF.
Engine is at normal operating temperature (if possible).
Turn ignition switch to ON position.
Do not start the engine.
Place a jumper wire across TEl and El terminals in engine check connector.
Count number of flashes from CHECK ENGINE light.
If system is operating normally (with no detected faults), the CHECK ENGINE light will blink continuouslyand evenly about 2 times a second.
Otherwise, the light will blink a number of times equal to the trouble code as follows:
The light blinks only (.5 second ON, .5 second OFF) when indicating a number.
The light will be OFF for 1.5 seconds between the first digit and the second digit of the code.
If more than one code is stored, the light will be OFF for 2.5 seconds before the next code is displayed.
Once all code(s) have been displayed, the light will be OFF for 4.5 seconds and then the whole sequence will repeat.

The diagnostic code series will continue to repeat as long as the check connecter terminals TEl and El are connected.
When finished, remove the jumper wire.
After repairing the malfunction, clear the codes from the ECUs memory.
Clearing Trouble Codes

All trouble codes must be purged from the ECUs memory after repairing the faults. Otherwise, code(s) would remain in the ECUs memory indefinitely and would appear along with a new code in the event of a future problem.
Remove the EFI fuse (15A) for 30 seconds with the ignition switch OFF to clear any codes. It may take longer than 30 seconds, depending on ambient temperature (the lower the temperature, the longer the fuse must be left out).

Trouble codes can also be cleared by disconnecting the vehicle battery. However, other memory functions (clock, radio, etc.), will need to be reset.

After the codes are cleared, road test the vehicle (as applicable for the fault) and recheck if any codes reset. If so, it indicates that the trouble area has not been repaired correctly.

it might not be noted there, but you need to locate this thing ... the diagnostic port, it's on the engine.

I also have a 92 ES300 5 speed. I can pull the seat out tomorrow evening to check the connector pinout to each wire. I would go to a salvage yard to cut a new section of the connector to replace the broken one.
