Key switch indicates power is on (sometimes), but nothing when you pull to start.
Assuming that the car is using a negative earth. (Negative battery terminal earths to the body/chassis)
The starter solenoid may have some bad connections. If this vehicle has a separate starter solenoid on the rear firewall under the bonnet, try bridging the big terminals with a jumper lead (red) and see if the solenoid/starter works. Some of them even had a press button between the main terminals. Try pressing the button if it has one.
If none of the above works, take the jumper wire directly to the starter motor from the batter possitive. If this causes the starter to spin, you clearly have a bad solenoid.....replace it.
NB! Be careful not to short out the jump lead against the engine or any other earth or you will see lots of sparks etc. You will not get a shock from this activity!
Possibly better to clip the jump lead to the starter main connector first and then touch the other end to the battery positive.
(I am assuming that the batter is charged up and properly connected.)
Also check the earth wire from engine to chassis. You can make do by using the other (Black) jump lead from the engine block to the battery negative.

Hi,from the clues you give I guess that the starter motor is in need of a service (worn brush gear) I presume that when it does not start that the engine does not make a cranking noise.
If the engine is cranking but failing to fire up, then it could be anything from the fuel pressure pump to the engine control system. there is a lot of clever stuff going on when you start your engine. Some simple things you should try first. Check visually that all vacuum hoses and wiring is secure and in good visual order( dodgy looking wires are prone to intermittent failure!... Do this next time it fails to start and recheck after gently adjusting ? wd 40 may ease problem temp. Also check service of spark plugs especially correct gap.
Make a note of engine temp/ and air temp. loose wires are usually more loose in cold mornings!.. starting enrichment may not be sufficient with a wide plug gap. Check battery for full power output on starting. will it pull the car on the starter /

If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.

Ignition relay or fuse could be the problem. When you turn the key to start do you hear a fuel pump kicking on and or do you have spark when you hot wire the starter (I know it's hard to check while trying to start it)? You can email me back and I might be able to pinpoint it more.

This is probably the ignition lock cylinder worn out or getting old. The TDM is most likely not locking the key in, but new cars are pretty tied into themselves. For now, just try leaving the key in. Use another one for the doors. Some cars have a small hole under the steering wheel/column that you can stick a pen or something in to release your key. Maybe just be ready for something else breaks, then you'll know what is wrong.

SOURCE: '91 LS400, trunk will not
If you hear the sound of the electric latch switch, then it's working but stuck somehow. Just put the key in the switch and turn it to the right and then pull up the trunk or ask someone to help you. it will open. I tried it today and it opened with me. It was stuck from inside by some kind of a broken plastic pieces. Just removed it and now it's working fine. good luck
