1984 380SL Cold Start Problem

Noticed lately my 84 380SL will not start when cold. The motor turns over strongly with a new battery, but the engine will not crank. I hear the fuel pump come on & stop after about 5 seconds (like I think it should). If I come back later (maybe 15 minutes after trying to start it), it will start perfectly. ALSO, for the last few times when it would not start, I removed the air cleaner cover & pushed down/release the round disk in the "throat" & the car started up perfectly. Was this by accident? If not, why would it start when pressing/releasing this disk? What are some other problems? Car idles perfectly once started with excellent acceleration & idles/starts perfectly when hot...just in the morning when cold, it will not start instantly.

I am new to the SL as I have driven MB diesels for 25 years! Any help would be greatly appreciated.

Richard
