Your public library will have a manual covering your mechanical repair. Moreover, they have the automotive shops online software called AllData. It is the best auto technician database available today. You can print out specific troubleshooting procedures, diagrams, step-by-step istructions, and soforth. The typical person cannot afford to pay for this service, just automotive dealerships, etc... that is why the public library made it available to everyone and for free to view and print out material.

On the side of your transmission will be a switch with several wires coming out of it. This is your reverse switch that turns on your reverse lights and most likely needs to be replaced

that would be the air bad light. You can pull the fuse on it if you wish. Otherwise, the computer will have to be reset.

Check the fuel relay in the fuse box they tend to burn out after a few years.. To access it. Remove the plastic cover by the cigarette lighter and remove the screw. Then remove the panel. This the big white relay on the left numbed 119 or 135. Replace it and see if this helps.

you are having a fuel delivery problem...and it could be caused by numerous things...such as a bad fuel pump, a bad cold sensor or warm up injector.  You haven't attempted to  solve any of these suspected faults...so take it to a mechanic for repair

There is no default code, the are unique to the radio. You will have to go to the dealer to get this code.

1991 Volvo 940 | Answered on Mar 15, 2009


In order to get to it I think you have to take out the lower dash and radio, open up the heating case to reveal it.

1991 Volvo 940 | Answered on Mar 01, 2009


You could try another key if you have one. The key has a chip in it that the computer must recognize before it will start. There is a possibility that the key transponder has failed.

If that doesn't work you will have to take it to a reputable shop or to the dealer so they can run the diagnostics. There could be a problem with the antenna, the module, or just a communication problem between the two.

Sorry wish I had better news.
