Default Won'runningtstay after high pressure fuel pump gaskets

I replaced valv cover and high pressure fuel pump gaskets. My LS460 starts and runs for a few seconds the starts backfiring like its lean. I think the high pressure side has not pumped completely.

Is there a procedure for bleeding the fuel system? Is there something else I need to do?
