Crank, no start

Push?

 

The coils are triggered by the pickup sensors on the flywheel as far as i know, if you have coil power then check the pickup connections behind the rear left wheel on the clutch housing. I think the earlier cars only had 1 coil sensor and the later had 2 ? There is also a rev counter sensor i think, others here might be more up on this than i am.
If yours is the earlier car with 1 sensor for the coils it would explain why it has completely stopped.

 

I doubt both coils would fail as well. Did your tach needle bounce at all during your drive? Any back fire at all?

 

I had a look at the drawing, thats a new one on me. The detail is hard to see but is that a double rotor arm ? I assume you mean 2 sets of points when you refer to pickups . Are you getting 12 volts to the pickups , there should be a condencer inside the distributor so check that is ok.
Final thing to check is the drive to the distributor, take the top off and get someone to crank it over, check it is turning is case the drive has broken.
From the lid of the distributor there looks to be a spring loaded carbon bush ? Which connects to the top of the rotor arm. Check this lot for good connections as what ever this is effects everything.

 

Do carb cars have mechanical or elecrtic fuel pump? I know they require far less fuel pressure than FI cars and pretty sure they still have electric pumps. Before ripping into expensive ignition parts like dizzy's, confirm fuel supply. It seems that a large percentage of these "crank no start" threads come down to fuel delivery. Always start with the simple stuff.

 

Have you tried putting a loose plug into 1 of the plug leads to see if you have a spark when cranking over ?
If you have a spark then have a look at the fuel supply - the diagram seems to show an electric pump so find the fuel inlet pipe to the carbs and put the end into a container and switch the ignition on to see if you get a fuel flow.

 

I agree with the suggestion to check fuel supply. I spent an inordinate amount of time chasing down what I was convinced was an electrical problem. Turned out that it was a fuel filter problem. Have you tried to start and run your car since it's been sitting in the garage for a while? If it starts and runs, I would start looking in that direction. I notice you said it hasn't started, but I don't know if that means on the day of disaster or if you have tried now that it has sat and cooled and settled.

 

I had a look on google and it appears that the single distributor originally came with 2 sets of points, but a magnetic system was available as an optional upgrade. There is a good lot of info to look at plus it ref back to some ferrari chat past posts re this system

 

As someone once said "99% of all fuel problems are ignition related" glad your back having fun.
