My problem: Starts fine when cold, once it warms up it wouldn't start. Cranks ok. Acts like no fuel or spark.
History: Installed new heater core and heater hoses, (previous owner had the heater core by-passed at the heater hoses). No prior problems with these symptoms.
Filled radiator and burped system using a spill-free funnel. Temp stable on gauge, fan comes on when necessary.
After filling and somewhat sure all air is out of the system. shut her down and cleaned up the work area... 10 min later went to start her and ...'no-start'. Cranks but no start. Check all connectors, etc. and about 10 min later she starts up and out of the garage I go. I get about 5 miles away and she dies... silence. Rolled into a parking lot and ... no start... cranks but no start.
Get a ride back home and begin my research on FiatSpider.com. Thought for sure I had a failing Temp sensor (at the Tee), causing the fuel not to pump. Waited about 2 hours, went back to the car and she started and I drove back home.
Now start troubleshooting. Cold...starts right up. Stop take an ohms reading of the Temp Sensor(at the tee). 4.7K ohms. Cold.
Start it, let it get up to temp, the fan kicks on just above mid-range on the gauge. Gauge drops down below mid-range(approx. 180 deg). Shut the engine down. Take an ohms reading of the temp gauge - 673 ohms. Slowly starts to rise after a few minutes.
Go to start.... No start.
Ok. Spark tester on coil wire. No visible spark. Pull distributor cap. This is what I found.
I guess before I go any further I need to replace the Pickup Coil. The insulation just crumbled away once I touched it. Could this be causing the problem? maybe making the Control Module fail?
I watched a Youtube video from international Autoparts on the magnetic pickup https://youtu.be/wzYxTlV8kKs @3:40 they talk about the magnet positioned with a stripe down. Mine wasn't. Does this matter?
I know I'm long winded, but hopefully I've provide infomation for someone in the future. I won't know if this fixes it till the parts come in. New Pickup Coil, Control Module, Distributor Cap, Rotor and plug wires on the way.

I would say that could be why too

Re: No Start when hot
The car won't run if the magnet is the wrong way. Follow the instructions on the particular magnet you receive. Pay attention to set the correct gap as well.
Re: No Start when hot
Yes, green corrosion. It wouldn't take much force to break the wires off. Just a strand or two still holding on at the pickup head.

That is the way I found it. It was running. Apparently changed once before...there was no screw holding the wire at the distributor entry point.
The pickup coil was also 'loose' on the mounting plate. Also probably not a good thing.

Re: No Start when hot
Had a similar problem. Check your fuel pump. Mine worked fine when cold, not so much when hot.

Re: No Start when hot
Update! Replaced magnetic pickup coil, Ignition Control Module, Distributor Cap, Rotor and plug wires.
Seems to have fixed the problem. Several hot / cold sessions and she runs like a champ!
