08 Mazda 3 no spark

So I was working on a guy's 08 Mazda 3 replaced cam sensor crank sensor 02 sensors did tune up after all this and 14 codes I was down to 1 code and it was the vvt sensor (it was replaced but I didn't do it ) but prior to that last sensor the car stopped firing it was running when I left it but ruff idle because the vvt sensor I started a new job couldn't get to it and he had a shop change the vvt sensor but it still won't fire and he had it towed back to his house that's where I'm stuck car cranks just fine absolutely has no spark on any plug won't even hit getting fuel just fine did it skip time ? It has compression as it cranks I'm stuck
