1988 Chevrolet R-30 not starting

    I started getting out my work trucks and getting them ready for spring. My '88 R-30 ran fine when I started it. Drove it for a couple of days with no problem except no heat. I figure it is the heater core, no big deal.

    I let it sit for a week until I could get around to fixing the core. When I went to move it it had a hard time starting. When it did start it belched out black smoke from the exhaust for about 20 seconds. Then the exhaust turned white and had a very rich smell to it. I let it idle for a while to see if it cleared up. The white exhaust continued and in about 1 hour it burned a 1/4 tank of fuel. I probably shouldn't have let it idle that long but I wanted to see if the check engine light would come on. I shut it off and decided to let it sit while I tried to figure out a cure by looking at posts on here.

    After letting it sit it won't start now. I can hear the fuel pump kick on when the ignition is turned on, I have spark, and I have no check engine light on. I unhooked the Map sensor to see if it would throw a code and it did. Threw a code 33. The thing is when I am trying to start it the engine accelerates if I press the gas pedal like it is trying to get fuel but just not quite enough. When I turn the key back from start it gasps a few times and shuts off.

    Any idea's? I am barely literate, mechanically speaking, so I am lost in the dark. Any help will be greatly appreciated.
