Been replacing a lot of parts, so numerous connectors aren’t connected. Everything worked fine before I started playing. Before I put all the parts back on, I’d like to check the new injectors at the fuel rail for leaks by just turning the key without engaging the starter, but the pump won’t kick in. No fuel in the rail. Hotwire to the pump was never disconnected. Battery is charged. Computer wire is connected. Ignition module & coil pack are not installed. Neither is the wiring harness to the injectors. If it means anything, the power master does kick in. Continue educating me, please. Am I missing a connection someplace, or is there a problem? Thanks
