67 twin turbo dart

Well tooth wheel is good and solid. Batch fire didnt change anything still back fired. Changed how the crank signal picks up and even tried putting the filters on crank and cam signal and still nothing. My father in law was walking by and said the back fore was on the drivers, so tomorrow when I get home will pull the plugs and ohms the wires, maybe it's a bad batch of NGK cooper plugs, will check the new ones in the motor and swap out to the old ones that worked when the engine ran before pulling it. Checking everything again, even each signal again to the coils and injectors and in order. Cylinder 2 injector suppose to light twice with the diode and did once, checked the other cylinders and went back to #2 and tested and it flashed twice like the computer says too.
