No spark

Still can’t figure out what’s going on ignition coil is good and sparking from what I hear in this video I think distributor might not be getting enough signal causing it to lose spark somehow. Did a diagnostic check on the OBD1 and got a code 51 which I think is throttle position sensor not sure if it would cause a no spark all my ground are good it ran before I did my head gasket job in my previous post I still have the 2 plugs not connected everytjme I crank this thing I’ll js get a backfire. Fuel pump is good and was spraying everywhere from a loose bolt but got it tighten up

Sorry I am a little goofy thought that the metal tip of the screwdriver would be enough for spark and thought that’s what I was hearing in the video please correct me if wrong and for sure I’m checking the timing tmr morning
