Then I shall be the first. Mine stalled in traffic years ago. The indications
are the main relay shuts down prior to rpm going to zero. Had no "fuel
pump" click from the relay when the car wouldn't restart. Most people
don't report their problem because most don't know for sure. And
most often, it happens only once in a blue moon.
One other note, this car never stalls in its 280k miles of lifetime.

I don't believe vibrations keep the main relay working once the motor
has started. At certain rpm the vibration is hardly there. ...How did you
come up with your conclusion?

Such a relay should be designed to NOT be affected by vibrations, for good or bad.

come on matt, there's limits to that. vibrations at what frequency?
what g's? how much do you want to spend? besides, it's not vibration
that causes the solder to crack - it's thermal cycling.
bottom line, the relay /does/ suck, but then again, a sub $60 fix on a
what is typically a >10yr old car is not that bad a deal. how much do
you need to spend to get a domestic past the 10yr mark?

Don't be silly... I was responding to the assertion that the vibrations help to
keep the relay working right. That's just silly - if a relay is RELYING on
vibrations from the running car to work properly, it's either faulty, or a
really poor design to begin with.
