main relay vs ignition switch while driving
Hi,
When there is a problem with the ignition switch
the car can stop even after the engine has ignited.
(I 've experienced that already!)
Can the same thing happen when the main relay has gone
bad?
I am afraid my Honda Accord has a bad main relay.
After (if!) the engine starts, is it dangerous to drive it?
Can the car stop suddenly even while running, or a bad
main relay basically affects only the ignition process?

Generally,ordinary body vibrations keep the main relay working once the
motor has started running.(and that the car's interior is usually cooler
once you have it running)
A bad relay affects the fuel pressure available;that's why the failure
moded is often "starts then immediately quits,then only cranks,no
startup,until the car sits for several minutes".
The motor uses up the stored fuel pressure,then starves and quits because
the fuel pump is not running,because the relay is not powering it.
The fuel injectors need a pressurized fuel supply rail.

Re: main relay vs ignition switch while driving
So if I understand well the car can die while driving,
when there is a problematic main relay?
(it affects not only the ignition process...)

No,it won't "die while driving".
Not with the typical main relay failure mode.

No,it won't "die while driving".
Not with the typical main relay failure mode.

kindly indicate the model and age and mileage - it helps a lot in giving

usually, if it dies while driving, it's the ignition switch - main
relays prevent starting, but not running, in my experience at any rate.

The main relay, IIRC, controls both starter and injectors... an intermittant one
could most certainly affect running...
