It's quite common on the old z's to plug up with debris from the tank. If you've verified the pump is still operational , and there's still no fuel flow, the only way to really check for sure is to pull the sending unit, clean the sock and check inside the tank. You could blow some air through the line to the front of the car after you disconnect it to check for blockage. It's very wise to use an inline fram style filter between the tank and the pump to catch any silt. The pump should be external. Mounted on the rail just by the tank. If you add a filter between the tank and the pump it can help catch debris before it even hits the pump. And the other thing they put in there is a fuel damper. It's designed to smooth the pulsing effect from the injectors for a cleaner gas flow. That is a very common item to bypass/delete
