Porblems Starting When Cold - Not Coolant Temp Sensor

[At-Least-It's-An-Evo]

Car: 91 Galant VR4

I put a new coolant temp sensor in it, there were two on the thermostat housing (I dunno if that's normal, it's a Galant VR4), but one came from a running car, and the other one is brand new.

The car starts when it's warm, it starts when its warmed up. It doesn't start when it's cold.

We sprayed carb shit in the IC pipe and cranked it and it started right away.

So... any suggestions? There's fuel coming outta the rail, but I dunno about the injectors (if they're opening) - doubt it.

There's spark.

So whatever controls the injectors from opening on cold starts isn't working.

Suggestions? ECU was changed to a working one, no fix there. I am gonna try another ECU JUST IN CASE, but I dunno.
