You have no spark and no fuel pressure, but it cranks?
When you say you did all your seals, what exactly do you mean? Did you replace the fuel tank sending unit O-ring? That would mean you had the pump out. Perhaps you damaged the wiring/broke a connector/broke an old, brittle fuel line.
Did you remove the distributor to replace the seal under it?
Some clarification of what you have done might help so folks can better advise you.
