OT, but there are a few petrol-heads here who might have useful
suggestions.

I have an old but good 91 Toyota Camry wagon,
The typical symptom is that I drive somewhere, park, come back to the car
an hour or so later, and it will not start.
The error code (in light flashes) is 43, which according to the manual
is:

Starter signal. No STA signal to ECU when vehicle stopped and engine
running over 800 rpm.
1. Main relay circuit
4. ECU

I discovered that a couple of the metal-case ones are very hot - too hot
to hold. These are labelled Fan no.1 and EFI main. Is it normal for these
relays to get very hot?

if it was mine i would first be looking at wiring connector issues to the
relay board and ECU due to age of car.
