Its an oldervehicle and sometimes with age they have to be babied to run right.i dont think theres much you can do to make it start and stay running right off the way it used to other than what youredoing now which is probably sitting in it with your foot on the gas until it warms up if my guess is correct. i have a 1994 suburban that i haveto do the same thing to because its just gotten where it doesnt like cold weather.

1996 Jeep Grand Cheerokee. Will only start will accelerator pushed and will only keep running if it is pushed. If I let off, it stalls completely.

Could be the idle air control valve or a dirty throttle body.
The computer controls idle speed by how much air enters the throttle body and intake.
You would need to check the throttle body and test the control valve.

High Idle when warmed up. 95 Grand cherokee 4liter. i can let off the gas and the vehicle will accelerate up to 30mph stays at about 1500rpms idling

Hi. Anon.
It sounds like your IACV, ( Idle Air Control Valve), is bad. I would go to the parts store, if you can drive the vehicle and have them hook a scanner up to your vehicle, ( its free) and pull the codes for you. This will give you a better idea of what is happening with your engine. Hope this helps. Let me know.

My 96 jeep shuts off in traffic and at stop lights

This sounds like a bad idle air control valve, but also make sure the throtlebody is clean, use a toothbrush and some throtlebody cleaner, spray and clean with brush, make sure to open plate by having someone hold gas pedal to floor, after cleaning if truck still stalls then replace the idle air control valve,

Fuel pump not running only in cold weather

Pumping the pedal on an injected engine does nothing, except varying the air intake amount. I would change the fuel filter (if badly plugged, it may be causing the pump to shut off early) and clean the idle air control valve.(which should regulate idle air flow, eliminating the need for playing with the pedal) The valve itself is not difficult to service, but is a bit delicate. It can be cleaned with carb cleaner. just make sure you do not turn the valve end around while cleaning, and re-install it perfectly straight. You may have a bad drain back valve in the pump, but this is less common than what I outlined above.(there are tests for this)
