If it won't even pop or fire on easy start, fuel isn't your problem - either nothing is getting into the cylinders, or there is nothing to make it go bang.
Compression test first. Make sure air gets in, and gets squished properly.
Then check you have decent spark the ENTIRE cranking time. Then make sure the timing REALLY is correct (if it was off, I'd at least expect a backfire or pop if the spark REALLY was working!). I'd go over the whole system, making no assumptions and using no preconceptions - it's easy to get wrong in the same way, repeatedly.
Even better, if you get an inline spark tester, you can see if it works under compression - sometimes spark "leaks out" the easiest path, if the cap is faulty (for example).
I'd leave the fuel pump disconnected and try get a get a pop on easy start, in case its dumping raw fuel into the cylinders.
After you can get it to fire/pop etc, THEN worry about the fuel getting in.
There is also the wire from the coil to the ECU that it uses to detect the spark and trigger the injectors - if it's not getting that signal, it will never open the injectors. You should have 12v on one side of the injectors, and the ECU earths the other side to open them. You can watch it with a multimeter. Each sides set of 4
Best thing for these old things is Rovergauge. You can tell if the ECU is getting sgnals, what they are and how it's responding.
Once again, I'd like to see a vid of it cranking, with decent sound
