Recently dropped in engine

[newjerZ]

ive been rebuilding my na 300zx for 9 months and i just dropped my engine in. i had 24 bent valves when i bought it so i took it apart down to the block, replaced all piston rings, gaskets, silcone hoses, fuel lines, repainted, and added air intake and headers. Now before i hooke the radiator up, the belts and all the vacuum lines, it ran and idled (rough as hell obviuosly). so i took the plenum off and finished doing the vaccum lines and installed the radiator. now it just kicks over and bogs down. its seems like its not getting fuel. im getting frustrated, any ideas? thanks

I'd start with checking fuel pressure since it sounds like a fuel issue. Make sure there are also no major vacuum leaks. I would also check the ECU to see if there are any codes stored that might help point to the issue.
