12valve should start right away regardless of grids/ no grids or advanced timing . ( with in reason ) .

Check filters , Fuel shut off solenoid and especially fuel pressure / fuel pump .
IF you have to prime the fuel pump via the lil rubber pumper ( say more than 2 pumps ) , air is entering the fuel loop somewhere
