Okay just did an engine swap and now I need to solve a fuel issue.

I'm fairly positive that I'm not getting fuel past the injectors in my 90 CRX-si.
I have fuel at the bleed bolt and fuel at the rail. I replaced the main relay and still no luck so I can only assume tht I have 16 year old clogged injectors, what's the cheapest way to solve this issue? Can I just buy a new manifold with injectors and rail, or is that outragously expensive? Or are the injectors easy enough to change that its better to just replace them, I don't wanna screw anything up.
