Grady is stressing the fuel safety, and he is right on. I have had fittings and hoses spring leaks when setting up for the first time. One particularly exciting time, a leak sprayed fuel right onto the live CDI box. Good times! This is when you will want a helper and a fire extinguisher. Other thoughts in no particular order:

There's not really any need to pull your spark plugs to build oil pressure. The engine will build enough pressure to 'bump' the needle within 10 seconds - you will be cranking longer than that to push fuel out to the injectors.

If I am having trouble with a no-start on a fresh MFI install, and/or I am not sure I am getting fuel delivered, there is a trick to try out. Again, a spotter and fire extinguisher are needed. Crack the fitting slightly loose between an injection line and the injector on that line. Have your helper crank the engine while you watch the line - fuel should leak out between the fitting and the injector if all is well. I have actually seen injection hardlines that wouldn't flow fuel due to internal gumming/corrosion/general crud.

Other things to check - make sure that you do a really good, thorough job correlating the injection system. These engines really don't like to start when the correlation is off. Use the factory CMA booklet and the Lee Rice guides, and you will be fine. Also, use the factory documentation on timing the MFI pump pulley to the crank.

Use all your senses when working that first start. Like was mentioned, have the air cleaner assembly taken off and set aside - it makes it easier to see/inspect/work.
-Touch various fittings and fuel lines for wetness
-Look at cloth braided fuel lines to get darker - that means they are soaking in fuel
-Smell for strong/increasing fuel smells
-Are the MFI pump fuel/return lines secured, so that they are not rubbing in the pump pulley and belt?
-Listen for strange noises/leaks etc.
