Hello,

My oil pressure light blinks once after start and then goes. Doesn't blink again. It only blinks if car is turned off for more than 30 minutes or so. Doesn't blink when hot.

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.
