I have a 1989 toyota pickup 3.0 crank no start. But if I spray starting fluid in the air filter it will start up and runs a a very low idle intell it dies. You can drive it around in tell you shut it off and then try starting it again and cranks over but doest start. I've replaced spark plugs, plug wires, distribution cap, and fuel filter and fuel pressure regulator.

Sounds like you changed everything except the most logical thing. Obviously it's a fuel issue whether it may be electrical or mechanical.
You first step should have been to test the fuel pressure.
Here are the required specs
FUEL PRESSURE:
At Idle .................... 33 - 37 PSI (226 - 265 kPa)
At WOT .................... 38 - 44 PSI (265 - 304 kPa)

I finally got back around to working on pickup replaced fuel pump. Now when its running it's seems to be flooding it self out it, after idling for a few you hit the throttle and it's real bogged down and starts blowing smoke and you can smell that it running rich. What would be causing it to run rich?

As previously suggested, read the fuel pressure and pay attention to what the pressure does when the key is first shut off.

Where would I find the procedure on testing fuel pressure?

Before we get that far we need to know if this truck is fuel injected or has a carb. It appears it could be either one.

OK, testing the fuel pressure on that vehicle is not a real simple thing to do. It will require a fuel pressure gauge and some adapters. This engine does not supply a service port for testing so you have to use adapters in the kit to "tee" into the fuel pressure line without "deadheading" it.
This is most likely something you will have to pay someone to do for you as you won't have the necessary tools and adapters to do this.
The purpose of the testing is to determine a couple things
1) Is the pressure too high possibly because the return line is restricted.
2) Is the rest pressure dropping off when the key is shut off indicating a possible leak in either an injector or the pressure regulator diaphragm.
You can pretty easily check the regulator by starting the engine with the vacuum line removed from the regulator and look for any fuel coming out of the vacuum nipple.
