HARD START, DODGE COLT, MITSUBISHI 2.0

I have a 1988 dodge colt vista. Starts when warm not when cold. Fuel pump is good, pressure is good, think it might be the engine temp sensor but don't know where it is located on the engine. 2.0 liter sohc mitsubishi engine. Once it starts, it runs well. Any other suggestions? Thanks

are you getting good spark? How new is the battery? Those are the two places i would start anyway

I found the engine temp sensor, standard part # tx32. Replaced it and cleaned the mass flow air sensor. Starts all the time on the first turn. Thanks for the reply.
