Is the oil pump electrical or mechanical

What is your question?

I turned the key on the wipers kick on as well as lights on th dash engine will start but it tick and rattled no oil is pumping. If it doesn’t do it engine runs quit and smooth it is random.some times it’s fine on startup and then drops out…

How long has your 2005 Dodge Durango had this problem?

A good while Not drivable
