I'm still guessing you've got K-Jet as you haven't said yet
The main boot is the big rubber union that goes between the metering head and the throttle body. K-Jet runs off intake vacuum, if you've been spraying easy start in, then you'll never have fuel because you will have removed the boot between the the intake and metering head.
Sounds like your spark is fine, so move onto fuel now. Again, assuming its K-Jet, you'll see two fuel lines running to the metering head from the left hand chassis leg, one is a return, one is a send. It doesn't really matter which, but crack the banjo bolt off the metering head and crank the engine - check for fuel flow (watch out for fire though!).
If there is flow then go to b) otherwise
It could be either the lift pump or main pump that isn't working. This is easy enough to check by cracking off the inspection cover in the boot above the fuel tank. Removing the send fuel line and cranking the engine. If it spurts fuel out, then its fine, but the main pump isn't - if it doesn't, remove it and find out why. If the main pump is at fault, sometimes it still whirrs away, but doesn't actually do anything - for this you'll need to remove it from the fuel pump housing (disconnect the two fuel lines off the tank pump to prevent it emptying fuel everywhere), sit the pump in a small cup of petrol and connect 12v to it (don't make it spark and set yourself alight).
b) Once you know the metering head is being fed, you need to check the injectors for flow. Crack off one of the injector fuel lines off the top of the metering head. There should be 5, one is for the cold start injector in the intake manifold, the others for the main injectors - remove one of these lines. Again, crank the engine and see if you have flow.
I'd put money on it being a vacuum leak, however, if you are unfortunate and it is not, then you'll need a fuel pressure gauge to tell exactly what's going on.
