It sounds like you have multiple unrelated problems. Did all this stuff happen at once???
Get yourself a good wiring diagram and set aside a day to go through all diagnostics. I would attack the most important stuff first.
Also... Though I have many years in the auto trade, You must remember that since I do not have the advantage of being there and being able to do tests etc, An accurate description of each problem, as well as history, is invaluable to current diagnosis. The better the info you give, the better the suggestions I can make regarding your specific issues!

1997 jeep wrangler has a long start. I have changed the fuel pump, camshaft sensor. any other suggestions

There is a head temp sensor and intake air temp sensor, either of which could make the mixture too lean. Check them with an ohmmeter. Not sure the exact reading, but bad ones usually go 0 or infinite.

My 93 jeep wrangler 4 cylinder temp gauge doesnt work right. when driving the gauge reads 0 when i step on the gas the gauge moves to the right temp. i have installed a new therm. new water pump new...

depending on how fast, this happens, could be an air lock in cooling syste, or a bad head gasket, or head. does the gauge ever go too high? can you hear gurgling in the rad, and does it ever push out coolant?

When you start and rev pours out black smoke and under power no guts and black smoke pours out

You will need to do some testing. check fuel pressure regulator, coolant temp sender, manifold air temp sender, manifold air pressure sensor, throttle position sensor, and remove and "read" spark ones may have a bad injector feeding them. A compression test may be warranted if all sensors check out. If you have a code scan done, ignore any codes for O2 sensor 'till all other components have been verified as good. Rich fuel mixture will trigger a code for that because the exhaust is beyond the ability of the sensor to read properly. A vehicle specific manual such as chiltons or haynes and a decent digital volt/ohmeter likely cost less that a one hour labor charge from any shop...a worthwhile investment you can use for this and other problem solving.
This is not really a ":solution" but I'd need to do that if I was working on it. I'm telling you where to look first.
Good luck

do you have a "check engine" light on? A bad temp sensor would give a wrong reading. Do you get heat from your heater core? Also make sure you are getting a good flow from catalytic converter and muffler so you know they aren't plugged heating up engine temp. Also make sure all your heat shields are in tact. Are you using 50/50 mix or mostly water? Though in cold temps you normally want to use more antifreeze less water, I would try more water, less antifrezze.
