Holley Sniper Issues

Got the basic Sniper for my 68 340, with the OEM style fuel module sending unit/fuel pump from Holley. I have a "Ready to Run" distributor. Hit the key the fuel pump comes on like it should, shuts off after a few seconds, go to start and it won't fire up. sounds like not getting fuel. Check fuel at the inlets it is getting fuel,(purged lines to get air out, lots of gas) if you pour a little fuel into the primaries, it fires right up and runs, just till it uses that little fuel. Any one got any ideas or had similar issues? Calling Holley monday. Thanks
Ok try this , take your air cleaner off get someone to operate the key while you look over the throttle body don’t start it just get the pump to prime you should get a prime shot . You will see fuel squirt from 4 injectors not a lot but enough to see if fuel is getting in .It me know before going to step 2 .This is not aimed at you but your fuel line in what side did you connect it too ? Reg side or other ? If that’s ok some times the connections on the injectors don’t sit properly on won’t fire it’s an easy fix by removing the side covers but don’t do this unless if it’s out of warranty from Holley because sometimes people tend to pinch the wires when installing the covers and than your screwed and they wont cover you . Sounds like something simple. One other thing what pump are you running ? Is it like the oe setup with the built in reg so you don’t need a return or you running a return line . Cheers
