If your lift pump is mounted on the side of the engine block and driven by the engines camshaft , the camshaft lobe may have fully stroked the pump which will prevent you from being able to manually pump fuel when you stroke the lever. You may need to bump the engine over a bit untill the cam lobe has moved from maximum stroke and you feel a little bit of resistance when you push the lever down. This resistance is caused by the pump diaphragm moving up to push fuel towards the filters. If it is an electricaly driven pump or a squeeze bulb this does not apply.
