Oil pressure lights blinks once after start

Good morning,

This may be ether the sender unit itself or you may have low pressure on start up from a oil pump that may have lost its prime.

I attached the location of the pump in the front of the engine for you.

I attached a YouTube video that shows where the pump is located and what needs to be removed to access it.

I would start with replacing the sender unit.

I attached a picture of the location for you.
