Re: 156 starting problems-its just not T sparking
It sounds exactly like my 145 Cloverleaf, when the Crank sensor (Also known as TDC Sensor) Failed.
I would out good money on it being your problem. I bet the car runs fine once it is running..
It can be tested by measuring its resistance with a multimeter. the connector is on the inlet manifold and is brown, disconnect and measure between the pins. It should give less than 1000 ohms. If it gives much more it is fooked.
