Your vehicle does not come equipped with an inertia fuel shut off switch. You will need to look elsewhere for this system failure. Possible causes could be: Anti theft (SRS) system, blow fuse, Relay, module, bad pump, wiring or connection or out of fuel. Please let me know if there is anything else I can help you with.

Something is being over looked. Diagnostics have to be performed to find out if this is related or a coincidence. I would first look, inspect and verify that the main accessory fuses are receiving 12 volts and are still properly grounded. What do you have for test equipment? Do you own a Power Probe, test light or multimeter? Please write back and let me know what tests you have run and what you have found so far. Most of these circuits are wired so they receive power when the key is in the ACC or RUN position and are activated from the Ground side.

The new sensor has to be programmed. You probably need a scanner that can communicate with that system. Check for related trouble codes.

May need new actuator. Try a slight lubricant like wd40 if that does not work. Try working switch back and forth. They usually start having problems when they get this old. You can have it replaced, but toyota /lexus is notorious for labor intensive repairs with can be costly if you take it to a dealer or very time consuming if you replace the actuator yourself.

Check your oil. If it is milky/tannish, then all signs point to the possibility of a cracked engine block. I hope not. That would mean a new or rebuilt engine and probably a few thousand$$$. Hope it's something else, friend.

The purge valve is mounted in the engine compartment, probably on the firewall. It is held on by two bolts. It has an electrical connector and two vacuum hoses and looks like the pic below. . Release the connector and unscrew the two bolts. Move the vacuum lines from the old valve to the new one. Bolt the new valve down and connect the wiring harness.

It's probably a problem with the shift lock system . This is a safety feature that won't allow you to shift from park into a gear unless your foot is pushing on the brake pedal . Brake switch sends a B+ voltage to a module (maybe) ,the module then energize's a locking solenoid ,to unlock the shifter . Google lexus shifter interlock .

The injectors open and close to feed fuel to cylinders based on data they receive from various censors. If the wrong info is fed to the ecm, this results in the injectors opening too long or too short what ever the case may be. Check out all of the sensors involved in feeding the ecm - Example: if there is a cold start sensor that is not working properly too much fuel will get in there and ......................

That red wire is not intended as a power source, you have shorted the unit to ground. Most likely the wire you connected to the lighter is a power out of the head unit not an power in. Check that with a meter or test light. The radio wiring colors for your car are below.
