I have the same problem occasionally only in cold weather, first start of the day. Am using the 5w30 full synthetic. Pressure comes up in 3 seconds like you say. Suspect it to be a sensitive oil pressure sensor rather than a real oil pressure problem.

Turn signal stalks have a history of broken wires.

Did the problem start the last time you changed oil filter? If so, change the filter with a quality brand as the problem may be related to a defective anti drain back valve in the filter itself.
Do let us know haw it sorts out. KBO mate.

Only started when the night time temps stayed below freezing for a couple weeks in a row. Four months after last oil/filter change.
