1990 Toyota Camry Fuel system

My brother in law recently purchased a used Camry. We managed to get the car to run briefly (10 seconds or less) twice, otherwise it won't start. It has fire to the plugs. We removed a fuel line from inside the engine compartment and with the key turned "on" no fuel comes out. Is this a fuel pump problem, or just not enough gas in the tank? We can blow air back into the tank, but only get air back out, no gas.
