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?
