Ignition coil and/or module and could also be a cam/ceankshaft sensor going south.

Check your fuel pressure regulator. It is on the fuel rail on the driver side of the motor. Look for a vacuum line that is hooked to the top of the regulator. Pull the vacuum line off and if gas runs out then the regulator is bad. I have the same problem right now on my Chevy. They are between $50 and $80. Hope this helps.

What can i do to start mt 96 chevy 4.3l 1500 truck, after ive changed fuel pump, plugs, plug wires, and checked voltage?

When you say you checked voltage...checked voltage to what? did you check to see if you had voltage going to the fuel pump? do you have spark coming from distributor to wire/ plugs, is the rotor ok? need to check weather your missing fuel, or spark so we know what direction to be looking at. you can try spraying ether/starting fluid in throttle body see if it will start up momentarily, that will atleast tell you weather its a fuel related problem or not.

This sounds llike weak feul pressure, the fuelpump may need replacing, the first thing to do is have the fuel pressure tested and if the pressure is low then have the pump replaced. the pump is located inside the fuel tank and the tank will need to be dropped to replace the pump, good luck ,

97 Chevy Tahoe is hard to start , problem is worse

This is just a guess- but I would try changing out the coolant temp sensor- this tells the computer that the engine is cold and needs a bit more fuel to start. If this is happening even when warm- look for a vacum leak.
