06 no spark

This truck is killing me. it is a 2006 tacoma 2wd 2.7 5speed with 195k. new head was done at 185k after poping a head gasket and learning about burnt valves. The whole fuel system expect the fuel tank and the metal fuel lines from the tank forward have been replaced. The whole evap system has been replaced front to back. And just about every electrical component has been replaced on the motor as well.
So after all this the truck is still idling like crap and stalling out and now won’t start because it has no spark. I just need semi decent ideas on what might b going on
