Yeah, 800 is way low for cold start. Sounds like an ECT issue, but not a classic dead one (which would throw a code, light up the CEL, and have the engine running rich all the time). Does the "cold" light come on at all? If your obd reader is up to it, for sure see what engine temperature is reading after an overnight sit.
