Get yourself a fuel pressure tester, make sure it holds pressure after the engine is shut down. Pull the vacuum hose on the fuel press. regulator & watch for fuel to come out, might take a minute or two.

Pull the vacuum hose off of the fuel pressure regulator and see if fuel comes out when you turn the pump on. If so, then you have a ruptured fuel pressure regulator. What year car is this? '88 and earlier have a cold start injector that can leak.
