Chris,
These are my routine procedures for initial run or start-up after an engine rebuild:
1). Disable the ignition system by unplugging the CDI or coil.
2). Disable the FP by removing the FP relay.
3). Turn the engine over by cranking the starter a few times.
4). Test run the FP for several seconds to check for any fuel leak in the system.
5). Replace everything back to normal.
6). With a fully charged battery, you should be able to start the engine on the first attempt or second.
