I have a 2001 Volvo s80 that ran out of gas. Now, my car will not turn over and it seems like my battery is low. I put 3 gallons of gas in the tank, and when I tried to start it I see message that says "immobilizer see manual". I know this is alot of symptoms, but your input will help. Thank you...

try to start your car with the valet key instead of master should start right up problem is master key.

Your immobilizer is enabled. Try locking/unlocking the doors with the remote five (5) times, this should remedy.

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck...i hope this helps...please take a minute to rate me a fixya.

The fuel pump which is located in the fuel tank beneath the back seat has gotten bad. Consider replacing it.

Cheers and rate this solution.

If you are talking about the thermo electric cooling fan, its operation is independent of the car's electical system. It is switched on and off by the engine temperature. When you park, the engine heat soaks upward to heat the thermostat turning the fan on. It will run until the engine cools down and the thermostat switches it off.
