On the VE pumps on our cars there is a vein pump in the pump that sucks its fuel from the tank. Some times they dont pump that well or if you just loose prime in the fuel system they cant suck enough to re prime the injection system. What I have done to get a prime back all the way to the pump is crack the return line at the pump take the fuel cap off and with an air line and some thing to half way seal it to pressurize the fuel tank and it will push fuel all the way up to the pump and fill the pump. then crack the injector lines at the injectors and crank until there is fuel squirting out the lines close each one as they start to squirt fuel by the time you get to all of them it should start.
