I have a strong feeling it is now the speed sensor on the flywheel that is doing this after the car is initially started.

However does this sensor also drive the tach? Strange thing is if I unplug the speed sensor but leave the TDC sensor in, the car will not start. I did it the vice versa way too, same result.
