It sounds like the ECU isn't getting the signal that it is cold. Fuel is getting to the fuel rail but not enough for a cold start.

How are you primeing it if it is fuel injected? starter fluid?

With starter fluid.

you could also check the fuel pressure regulator. they get weak bleed pressure back to the fuel tank and dont hold enough pressure in the fuel rail for start up until you crank them for a min.

I will check the fuel pressure but once I spray prime it it will run. Just won't restart unless I prime again.

Ignition switch is a possibility. Try turning the ignition switch to the on position and jump the starter. Large B+ terminal to the small s terminal. If it starts the ignition switch has a flat or burnt or broken spot in it.
