Hi,
I need to ask a few questions.
Does the car have around 200k on the odometer?
By chance do you know if the starter has never been replaced?
If so, the problem is most likely lies in the solenoid on the starter. It has worn just enough to not always make up its contacts inside it.
When you go to crank you may or may not hear a click and the panel lights go completely out.
You might think you have a dead battery but the lights are staying bright in broad daylight.
If you can find a flat iron on a piece of metal about 3/16” thick and 18” to 24” in length will weigh about one pound.
I made one up that is completely insulated with black tape used to wrap around black iron plumbing pipe. It is thin to slips down by hoses and not conduct power in case the battery cable terminal is naked down there.
This works fine until the solenoid gets really bad off or you get tired of the inconvenience.
You can try thumping the solenoid and that should start the car after a couple raps on it. If this works, whether hot or cold, then you know you found the problem!
The starter solenoid or the whole motor needs servicing.
It has been my experience that the rest of the starter can be in good working order but there can be a lots of carbon inside from brush wear.
I usually find them to still have plenty of length!
This depends on the tune of the car over the years of service, that dictates the amount of wear in there!
It comes down to only the solenoid is running out of enough stroke inside after 20 to 25 years.
There is a slight modification that can be done to the solenoid o keep it working.
I have written it up before on to other posts for the same issue.
FYI
On 240’s, up too, but not including the 1993, there is a remote start wire, located near the oil level dip stick on the firewall harness. It just sticks out there going to nowhere.
It has an insulated tip that needs to be defeated internally to get power on that wire.
This remote wire can be used to roll the starter over anytime you can connect a wire from the positive battery post to that wire.
You will need a wire long enough to reach that distance.
If and When you do this, the starter engages the the start motor, so make sure, you are out of a manual gear, in Park or Neutral on an automatic transmission.
Putting or leaving the ignition switch in position two (run) the engine will start and keep running!
Be knowledgeable of what you are doing!
You can rapidly jump power onto this wire and maybe get the solenoid might to connect up without having to have a rapping tool.
As far as I know, Having a person in the car, that listens to that type music, doesn’t work! (:-)
Hope this is it and Good luck!
