Beyond that, there are a few other possibilities, though less likely than simply being out of gas:
* Fuel pump failure (coincidence): Running out of gas can sometimes damage the fuel pump if it's already weak or nearing the end of its life. The pump might have been running dry and overheated.
* Air in the fuel lines: Running out of gas can introduce air into the fuel lines, which needs to be purged before the car will start. This usually resolves itself after adding fuel.
* Electrical issues (unlikely, but possible): While rare, running out of gas might coincidentally coincide with an unrelated electrical problem preventing the car from starting. This would require further investigation.
To fix it:
1. Add fuel: This is the most likely solution. Add at least a couple of gallons of gas. You may need to wait a few minutes for the fuel pump to prime.
2. Try to start: If it still doesn't start after adding fuel, try again after a few minutes.
3. Check for other issues: If it still doesn't start, then you should check for other problems, such as a faulty fuel pump or a different electrical issue. This often requires a mechanic or diagnostic tools.
In short, the most probable reason your Blazer won't start is simply that it's out of fuel. Adding fuel is the first and most likely successful step.
