1990 trooper 2.8L V6 Gasoline starts hard if at all,fires then backfires then runs a few sec then dies

Have you cleaned the throttle valve and the air bypass idle speed control valve? If not do that. When they get really gummed up from backwash from the combustion process they cause this problem of stall on cold start.

Just had an engine rebuilt not getting oil pressure

you need to pre pressure a new /rebuilt engine so you get oil into all the galleries , connect an electric drill to the oil pump drive and spin for a good 3-4 minutes , connect a pressure gauge as well so you can see the pressure build up

My 1994 Isuzu Pickup wont start when its below 32 degrees. Ive changed the gas filter, fuel pump, it just doesnt want to start when cold.

Below 32 degrees ( Fahrenheit , I presume) can cover a wide interval of temperatures. It could be the battery. You should consider installing a battery with a higher cranking power. In the colder parts of Canada, people install an engine warmer contraption. The device is kept connect to an electrical outlet overnight. In some places, it gets so cold that electrical outlets are available at some parking spots.
