Have your alternator tested. It sounds like a voltage problem to the ignition system. If the alternator is okay check things like ground strap, plugs, wires, coil packs, and the circuit board where the coils mount.

1994 Chevy 3500hd 6.5 turbo diesel starts then stalls. I have to pump the gas pedal a lot before it starts again. Once started, it runs rough. Specially when I step on the pedal.

As there is no connection between the accelerator pedal and the fuel system then pumping the pedal will have no effect.. I would be checking and bleeding the fuel system from the filter to the pump and checking for a leak in the fuel supply system. Hard starting and running rough is an indication of air in the pump and in the lines to the injectors.

When starting in cold weather, the car races and then almost stalls (revs go between 400 to 2300), after it warms up it's fine.

I would look at the coolant temp sensor.  The sensor is what controls the idle when temp is below a certain degree so it wont stall because it is cold.  To over ride this feature you need to press the gas pedal to the floor then start it.  If it works as it should go to your local parts store and buy a coolant temp sensor and change it out.  If you are not familiar with your car you can buy a Haynes manual and it will walk you through the process step by step.

Sounds like your fuel pump is going bad! The more you press on the pedal the more demand is on the pump and it cant keep up cuz its junk. Try to limp it to a shop to replace it, unless u wanna do that yourself.....
