What could cause No Oil Pressure
I got a 03 6.0 in a project ive been working on for a while. Bought the motor that was suppose to be good with only 50,000 miles on it. I finally got it running Friday. Fired it up. No oil pressure at all. I have a mechanical oil pressure gauge. I took the fitting out behind the intake to make sure it wasnt the gauge. Not even a drop came out while it was running. So I thought oil pump. Put in a brand new Melling pump today. Poured oil down the oil pressure sensor hole to maybe help prime it. Nothing. Didnt even squirt the oil that I pored in it out. So what do yall think. Spun bearing? Didnt sound like it while it was running. Ive run it probably a total of 45 seconds to see if it would build pressure. Anything else I can do before I give up and pull the motor?
