If it had a cold start system, it would consist of a thermostart element screwed in to the intake manifold and supplied with fuel via pipe from the injector pump gallery. There would also be a thermostart button in the cab.
Just tilt the cab and look at the intake manifold and it should be clear whether it's there or not.
Re - the cold start. Check the air filter - make sure it's clean. Check the water separator/pre-filter -make sure the element is not clogged up.
