No oil pressure on new build
I have a friend that is working on a 37 21 stud that was Rebuilt 30 years ago. When starting, it has no oil pressure. Removed the sending unit from the rear of the engine and there is no oil coming out when cranking it over.
The fuel pump is working.
What could be some of the issues on a new build and no oil pressure?
What else can be checked?
