If you find out it's getting power, double check the fuel system. Make certain the pump isn't running. I have a 94 i bought to rebuild and had a very similar problem. I bought it not running, and the guy i bought it from said it was an electrical problem cause he tried spraying a little starting fluid in it and it still didn't even try to start. So when i got it, i replaced the plugs and wires just because they needed it, and if fired right up. I though my problem was solved. Then over the next day or so it began starting harder and harder till all it did was crank. Here what it was was the fuel pressure regulator was bad and it was letting to much pressure to the injectors and the injectors were spraying to much fuel when they would open, so much that when you'd take the spark plugs out of all the cylinders and crank the motor, fuel would shoot out of the holes for the plugs. I replaced the regulator and it ran fine after that. It was dumping so much fuel in the cylinders that it was more or less drounding out the spark. Your situations sounds very similar.
