It ran fine last Saturday. On Sunday, it seemed a little sluggish, and the more I drove it, the worse it got. It started dying every time I stopped, and I had to floor it to get it started. When it did start, it belched black smoke and had no power. It finally would not start at all. I've tried ether (not a cough), replaced the coil and the O2 sensor, but nothing seems to give me my spark back.
Are you getting power to the coil? If coil voltage is low, suspect the radio capacitor is shorted. If the voltage is good, the problem may be the ignition module. One other possibility is a problem with the distributor pickup coil or connector. See 2nd page at link below.

check the aux duel tank switch you can pull the switch out and if you cant tell if its bad or not expose the wires going into it take another piece of wire and hook it into a fuse port then toach it to the difrent wires coming from the switch and if its the switch or a bad relay you will be able to tell because youll be able to hear the fuel pumps turn on the same thing happened to mine a couple of weeks ago i just went down to the junk yard and switched it all out

un plug the fuel injector and see if the raw fuel smell, goes way, if it does the injector could be stuck open. if this is the case the more you run it the more fuel is getting into the crank case, this can wash the bearings and ruin the engine, check the oil see if you smell fuel if you do, you will have to pull up the injector rail with all the injectors and cycle the key one time, watch that injector to see if it drips fuel after the rest have stopped . if it leaks replace the injector all the injector o rings and change the oil.
