1990 Chrysler Le Baron Car starts runs few seconds then die

I have disconnected the fuel line from the fuel filter and the pump seems to work OK. I arn a diagnostic via the check engine light and got the following codes, 21, 41, 25. The code 21 is the O2 sensor which I have replaced. Code 25 is ASI Circuit and I replaced that from another engine that I have. I also get code 41 which is field circuit. I believe I am getting that code because the battery has been run down trying to start the engine. As I said in my previous post the engine will run fine for about 15 to 20 seconds and then die. I haven't check the coil yet but will be doing so, I also will have the alt. Checked just in case. Would the map sensor affect the car this way?

I wish to thank everyone for their help. After replacing the coil (I had another one laying around) The car runs. I will take it for a full test drive tomorrow. I like to let everyone know that this car has 300,000+ miles on it and still is a good car. To the people that have a convertable and are having problems with the back quarter window motors not working. I have an answer. If you take the windows and motor out, you will find a small hole at the bottom of the motor. Squirt WD40 or simular product and work the motor it will free up. This was told to me by a gentleman in a salvage yard. It does work. However it is not an easy job to get at the window motor. THe back seat has to be taken out and each side panel and trim removed.
