'rocc won't start

Tested coil and module. Coil was fine, module tested bad. Replaced module (5 year warranties rule), got spark (real good spark too, I zapped myself. Oops.) Still nothing. Spark is going to all 4 cylinders, so the timing belt's ok. Talked to a mechanic yesterday, he said to unplug the cold start thingy and see what happened. I did this after work today, it fired, turned a couple revs, and quit. I plugged it back in and it STARTED!?!?! Needless to say, there was some rejoicing, then cursing(Don't leave your toolkit on a rough running engine). After picking up my tools, I tried starting it again. I cranked it a few times and it started AGAIN!!! It ran rough till about 2000 rpms, then smoothed out. OK, this is kewl, just needs to run, I thought. I took my foot off the gas, it stalled immediately. I cranked it again, it started again, and still wouldn't idle. Then, it stalled again, and will not start. It turns over, but will not fire. WTF???
