Car is a 2004 straight Boxster, manual, 30,000 miles, battery is good.
Problem is that on the first start of the day, typically at temperatures of around 50 degrees F., it takes up to six seconds or so for the starter to activate once the ignition key is turned to "start." At that point, the start is strong and normal, but nothing happens for six seconds. Further starts during the day are perfectly normal.
I have replaced 1/the electrical component of the ignition switch and 2/the small starter relay on the left side of the aft baggage compartment, but neither has caused the slightest change in the situation.
Should I simply replace the starter solenoid, or might there be another cause for this anomaly?
