Hot Start trouble. Please Help 200

Hi, let's try this again. My computer is acting up!
I have a 1985 245 turbo that has been acting up lately. I took the car to the shop for them to repair the cooling system. It turned out to be the head gasket. $1300, a week and many headaches later I got the car back. They wanted to charge me $200+ for a new fan clutch before I left. I decided to do it myself for $40. It worked out great and the car is cooling perfect. Now the car won't start when the engine is warm!

It starts okay when the engine is cold. I have to try a couple of time and keep the gas pedal on for 30 seconds to keep it running. When I drive it around then try to start the car it doesn't even start to "catch on". I mean it just turns over and doesn't even come close to starting. I have a air to fuel ratio meter connected to the O2 sensor. Normally when the engine is cold the meter will stay in the Stoichiometeric area and not move until the engine is warm enough. I think this is becuase the O2 sensor doesn't really work until it gets to a certain temp. When I got it started cold the meter was going quickly from rich to lean. I could hear the fuel system pulsing to this sound. The meter and the pulsing noise were moving to the same rythim. Could my O2 sensor be broken? Or what could it be. I know it's getting fuel because I have flooded the engine a couple of time trying to get it started. I have new spark plugs and wires, but I haven't done the cap and rotor yet. What should I check and do? Thanks a lot. You guys have saved me $$$$ and have given something to do.
