Boxster start up noise

[mptoledo]

just a thought, but before I replaced my ignition switch, I heard I whining noise similiar to yours. I think it was the starter of flywheel or something. The sound immediately went away as soon as I turned the key back to the run position. Since I replaced my ignition switch I no longer hear it.

Does your key stick for a second before it goes back to run position?
If your key works great then ignore this post.

If it's starting a few seconds after the engine starts, could it be the secondary air injection pump?

This occours as the motor starts only for 1/2 second and stops. It does it on an intermittent basis.

I have the same noise intermittently on my 99 also, and read elsewhere on these forums it's a pinion in the starter. It gets gunked up, needs to be removed, cleaned, lubricated, and reinserted for another 80-150k of trouble-free operation.

While I would like to beleive that post. (its simple and cost effective) I have also read that it is a worn starter bushing which needs replaced. Starters are about $250. and I would not know where to get the bushing part. Also have been told it coud be the mechanical and the electrical portions of the starter switch hanging up. Have also heard secondary air pump (not sure about that one however)

My 98 does the same thing. Up until now I put it up to the timing chain not being lubed at startups. After the car has run I don't get the noise.

I you haven't found it by now, it's the starter pinion or drive. You may replace it or lube it to fix it. Mine did the same.
