I have the van listed above G30 with a 350 v8 engine. My temperature gauge and oil pressure gauge are not working at all. I have no reading at all. I would like to know what's the most possible common causes?

Thank you

Hi,

The first thing I would check is at the sensors related to the oil pressure and the temperature sensor. Check to see if anything is damaged, disconnected, or corroded.

I attached a pic below showing locations. Let me know what you find or if you have other questions.

Take care,
Joe
