Yesterday we replaced the ignition unit and protective cover on my friend's
'90 300 SL. We put the old tumbler on it. The started cranks but does not start. I do not see any ignition at the plugs.
Do we need to reset anything?
ALLData software indicates that ignition unit and tumbler is supposed to be replaced as a whole and the tumble cap is not supposed to come off so I am surprised that the dealer would sell the untit without a new tumbler.

Thanks
