Here is a roundabout answer: spray a flamable such as carb cleaner or starting fluid into the throttle body-(f/i?) and then crank it. Other wise, hook up a fuel pressure gauge and check while cranking.

How can you tell by troubleshooting if your problem is the fuel pump?
pressure test line comming from fuel tank,one of two ways,1.disconect line from fuel filter on side where fuel line connects from fuel tank,if pressure 26psi to 35psi reconnect line to filter and check your line on other side of filter if pressure holds your fuel pump and fuel filter are ok,the other way is to disconnect inlet line from tank to fuel regulator and check your fuel pressure,the only thing with this method is if your fuel filter is clogging or clogged you will not get an accurate fuel psi.you can also check your fuel regulator,you fuses,or your relays to anything that has to do with your,depending on what type of car you have

What will stop fuel from flowing through outbound reserve line...no pressure. when there is still good pressure and fuel feeding up from the fuel filter line on a 1990 300zx n-a?
Well, i suppose if your injectors are using all of the fuel (super rare) then there would be no fuel coming back to the return fuel line. However, since you say there is NO fuel pressure, I would check out the fuel pressure regulators and the vacuum lines connected to them. The pressure regulators are located on the top of the engine and are directly in line to the fuel line. They are connected between the fuel rail (where all the injectors are fed from) and the metal fuel rail on top.
