Manny.....
I guess my first question up is.... was the fuel fresh on this incident and that last time before you tore it down?
I'm guessing you have spark.... especially since you changed them out and the coils......
how long has it sat this time and before? is the tank liner intact? ...
Just from what I've gotten from you message, it sounds like an injector(s) are plugged...
Throw some more info this way.....
