Check distributor? They’re known for chewing the teeth. If not set in right it won’t run, and if even slightly off will throw a code….

The crank sensor and the distributor would set a dtc had they failed. Fuel pressure wouldn't so I'd verify that and any systems that wont set a code. Alway go with the revised Delco fuel pump.

Check the cooling sensor next to the thermostat, the contacts will often become corroded and will give you symptoms of a choke being on all the time.
