Priming the fuel system

After a year plus of sitting, I finally have the new engine in my 745t. Everything seems to be hooked up correctly, but it still won't start. It turns over fine, but it won't start. At this point, the two obvious culprits are fuel and spark. I'm troubleshooting fuel first.

Can I prime the fuel system by simply turning the ignition off and on 10-15 times, or do I need to jump the fuel pump fuse so the pump runs constantly for 15-20 seconds?

Thanks,
