may never have been the plugs. have your fuel pressure checked for possible fuel pump failure.

ck fuel pressure with a gage it is fuel injection
Did you replace the wires in correct order? Maybe left anything disconnected? Recheck your work. Need more data.
I also think possibly fuel pump. I have found that if your able to have someone try and start the truck while you pound on the tank with small mallet. it may start. Then you know its a fuel condition.
