Would anyone know if the cold start injector fires everytime regardless of temperature. I know during cranking the wire shows 12 volts.

That's the power side, crank only, on ground side, it is controlled by a thermostat or temp. sensor

Would you know if bypassing the thermswitch so it fires every time regardless of temperature would be an issue?
I have a long crank time but if I force it to spray it cranks fine. Or to get it to start normal I have to tap the throttle open a bit

Sounds like a bandaid, I would not alter the cold start system, What is the vehicle?
