Nanocom would be very useful for checking the afore-mentioned crankshaft position sensor operation as that is the only critical sensor. Nanocom cannot check fuel pressure, but as you have some fuel getting to a removed injector, it should be enough to run. Even a dud throttle sensor wont stop it from starting and idling.
Other than that, it has to have enough compression, which can be compromised if the oil has been allowed to drain from the valve lash adjusters (similar to hydraulic lifters). I've not heard of this actually happening but there is a warning in the workshop manual about storing lash adjusters upright to prevent this and if the engine has been upside down for some time then maybe it could happen.
Hopefully its just something simple.
