I would check to see if the radiator is leaking, even the slightest leak (like I had) can cause problems. After you check the radiator check the hoses. If it was the heater core your passenger side floor would be soaked in coolant.

Could be the lower intake manifold gasket... You have to get like a mirror to check though.

The only thing that I can think of is maybe it's a bad thermostat... I'm not real good at diagnosing things lol. I just know about stuff I've already been through with my truck.

put uv dye in the coolant and get a uv light and do a pressure test on the system. when was the last time the cooling system was flushed? when was the last time the cap was replaced? what is going on when you try to start it? is it clicking? is the motor cranking but not actually starting? when was the last time you changed the fuel filter?
