I have a 1989 Civic Dx. It started a new problem today. When I crank the car up, it actually starts, runs for about 1-2 seconds, and cuts off. Restarting the vehicle results in the same symptoms. On about the 4-5 start, the engine will stay running. This occurred several times today. When I left work, the same issue occurred, only the check engine light came on. I checked the ECM for error codes, and the only error code it displays is error code "1". This says oxygen sensor, but I replaced it earlier this summer. Also, the ECM always shows this error code, so this is not new. Anyone have any suggestions? Also, FYI, I replaced the Main relay this summer. Thanks in advance.

 

my ignition switch went bad and started to do the same thing....would even cut off on me when i was driving down the street. I replaced the white piece on the back of the switch and haven't had any problems with it in 2 years. Also my fuel pump started going bad and did the same thing.
