1991 audi 100 fuel
 

are there any fuel sensors or relays that would stop gas from getting into
injectors until the car is warmed up? The car runs fine after i have to
start and stall it about 20 times

Fairly typical to see this condition caused by a temperature sensor
going bad. It is on the head, adjacent to the inlet for the top radiator
hose.

When bad the ECU thinks that the engine is already up to operating temp
and turns off the cold start injector.

It could be faulty cold start injector, although failure of injector
itself is very rare occurence. It's electrically operated so it could
be bad wire/connector too.
