I took my car in to get smogged last wednesday and it failed the visual inspection because the Check Engine light didn't work. I was reading through my chiltons manual saying that it probably was the bulb or the ECU. So I took the gauge pod off and replaced the bulb and it worked but the check engine light wouldn't turn off so I read the ECU code to see what the problem was and It turns out to be an Air Temp sensor on the intake manifold that wasn't working properly. I changed out the sensor and the ECU cleared out but the check engine light stopped working (usually it turns on briefly when you start the car and it turns off after 3 seconds).
I figured the bulb burned out again so i switched it with a new one and doesn't work. I used my mult meter and checked the voltage across the connector that feeds power to that bulb and it reads about 10.7v and checked a few other lights next to it to make sure its the correct power output and they all put out about 10.5v - 10.9v. I put the bulb back in its socket and wire harness back and the bulb didn't light up so I tested it under load and it only puts out 1.49v. I checked all the fuses and connectors and they were all fine. After giving up and putting it all back together the car won't start up. I checked all connections again and put it all back together and it still doesn't work. The starter motor turns over and sounds like its going to start but nothing. I think my ECU Fried because it smells like something burned in the ECU.
My car is a 1991 Honda Prelude Si (2.1L)... Any help would be appreciated and please don't thread crap go somewhere else if you feel like it.
