Question about 1998 Isuzu Hombre
Has new fuel pump,good spark,good compression,good battery,good starter. will not start next morning until temperature goes above 32 degrees,
Run fault codes and look for a faulty ambient temperature sensor as if it is faulty the ECM will not know to enrich the mixture ( like pulling on the choke)

Well, could be many things, but first and easiest, check the dist. cap and rotor, and all the plug connections. Any moisture will freeze and short out the ignition system. Also change the fuel filter. If you get the slightest moisture in the fuel it will lock up the filter when the water freezes. Could be a relay, probably "engine relay" that sticks when it gets too cold.
Some starting points I hope.

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

cam timming is possibly out due to gear reduction set up in heads
suggest remove rocker covers and make sure cam lobes are in this possition as well as all other timming marks luckily these engines (V6) are free wheeling (wont bend valves) set up like pic below
