However I replaced both fuel pumps and had no issues turning the engine and verified the rocker moved accordingly. I should be getting 4Mpa but I'm getting fuel basket pressure at the rail sensor...
The only thing I can think of is that there is something wrong with the DI Fuel line where its getting pressure but not able to flow as much as it should be able to.
