No oil pressure after rebuild

[dragon]

Help. Just completed a engine rebuild. After letting engine turnover for several minutes (on battery) no oil pressure was registering on dial. Fired engine up briefly, but still no pressure. Any suggestions? Regards

Thanks for your help - problem now solved! I turned the engine over for several minutes, filled the oil filter, filled the oil cooler and filled all the oil pipes with oil. Cheers!
