My 1994 volvo won't start . the car sounds like i...

Sounds like the fuel filter is dirty... When have you replaced it last? Possible that the pump is bad but I would start with the filter.

need more details

Have the dealer look for soft codes and to check the connections to the starter and the battery and to check the alternator for proper charging. Volvo alternators have a circuit inside of them that when it goes bad it will cause the car to stop running without warning.

turn ignition key go back of car you should be able to hear a humming sound under neath car if you don't hear anything your fuel pump is bad or disconnect fuel line from injectors and try to crank car if the area is wet pump is working

possibly broken timing belt.

Please see my tip at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines and let me know if you have questions.

COULD BE A RESTRICTED FUEL FILTER.

sounds like a bad ignition switch, no the key clylinder but the actual electrical switch.

I am a volvo tech and your problem is fuel pressure ralated and i had same problem in 1995 850 turbo and the fuel pump was the problem and a used one is around 35.00

when the arrow light is flashing it means the car is in what they call "limp home mode" its supposed to reduce power output in order to prevent further damage to the vehicle. usually kicks in when you're "hot rodding" the car for a long period of time. however i have no idea why it would come on if you just shifted from 3 to L unless the computer felt you were endangering the transmission

Try cleaning the throttle body and air idle control valve (IAC). The computer kicks the idle up when the a/c is on, if your throttle body or AIC valve is full of crud it will idle very low and feel rough.
