1991 Volvo 240 No Start After Empty Tank
One thought is that when you run out of gas all the crap from the bottom of the tank gets sucked in to the line. Could be plugged line or your filter took a big load and plugged up.
Suggested Repair
Remove the air cleaner and pour a very small amount of gasoline into the carburetor throat, then try to start. If it starts and dies again, check for a stuck-shut float or no fuel reaching the carburetor, including the fuel pump, fuel filter, and lines. Debris from the bottom of the tank after running out of gas may have plugged the filter or line.
Conversation Summary
The owner of a 1991 Volvo 240 wagon ran out of gas, refilled it, and it still would not start. A friend suggested priming the carburetor. The expert said gas engines usually should not need priming, and advised putting a very small amount of gas in the carburetor throat after removing the air cleaner. If it starts and then dies repeatedly, a stuck float or a fuel delivery problem such as the pump, filter, or a line plugged by tank debris is likely.
