[s-cars] Troubleshooting help

[Varon H. Fugman]

Sounds like the relay for the after-run turbo cool-down system.  Turns on
the little electric water pump and the electric fan based on a temperature
sensor.  When the engine is good and hot, this system should come on about 5
minutes after shut-down and run for maybe 10-15 minutes.  The coolant flow
helps keep the turbo bearing from getting too hot during the post-shutdown
heat soak period.  I belive this is the best factory-supplied turbo
after-run system in existance (and should help with long turbo life.)

However, I don't think failure of that relay would cause a no-start
condition.

Might be worth it to pull a spark plug and see what it looks like.  Could be
wet plugs from moisture (condensation) built up in the intake tract from all
that sitting around.

A follow-up...I haven't looked at the fuel pump relay
yet, but what is a "LDA/KSB relay"?? It's in the
passenger's footwell, in the relay box with the airbag
light relay. It's also listed as the water pump and
auxiliary air blower relay. If this had failed, would
it cause the car not to start??

Thanks again

Mike
