Sounds as if you are doing it correctly but you are on wrong stroke of #1 cylinder.

Remove valve cover so you can see valves/rockers for #1 cylinder and line up marks where you installed pump,

if both rocker levers are tight pump is 180 degrees off.

Remove pump, turn engine over 1 full turn, reinstall pump and it should fire right up

You could also just remove pump in any location and turn engine over 1 full turn and reinstall pump.

Make sure to turn exactly 1 full turn

Also make sure shutdown solenoid is getting power with key on and during cranking just to be sure if you had no smoke while trying to start.

Any problems let me know I'm happy to assist!
