Too Much Fuel --Problem Solved--Update

Last week I had reported that my injectors were staying wide open and dumping raw fuel into the cylinders and the vehicle wouldn't start. Several helpful suggestions were made. Here's the follow-up:
After following the flow charts in the shop manual and checking everything per the outlined procedures, it turns out that the ECM was bad. Pins D15 & D16 were internally shorted inside the ECM causing the injectors to stay open as soon as the key was turned to the "on" position. After I installed the new ECM, I drained 6 1/2 quarts of oil/gas mixture from the crankcase. So, Monte SS you were right...faulty ECM....thanks again for the help. (While swapping the ECM, I noticed that the previous owner had installed a Hypertech PROM.)
