what do you mean by no oil? No oil psi per eng sensors or did you remove the high psi hose from the cyl head and have no oil from pump?

Does the base engine oil build pressure? If it does(more than likly it does) you need a new hp oil pump. Not to pricey and fairly easy to install even comes with a new fuel pump and ipr on it. Is the ipr know good or just new I have had one new ipr that didnt work.
