If your Blazer won't start after running out of gas, the problem is likely due to:
* Air in the fuel lines: Running the engine dry can introduce air into the fuel system. The fuel pump will usually purge this air after a few seconds of cranking, but it might take a little longer. Give it some time and try again.
* Damaged fuel pump: In rare cases, running completely out of gas *can* damage the fuel pump by causing it to overheat (as it's trying to pump air). This is less common in newer vehicles.
* Low fuel pressure: Even if the pump is fine, there might be a drop in fuel pressure that needs time to recover.
What to do if your Blazer won't start after running out of gas:
1. Add gas: This is the most obvious step! Add several gallons of fuel.
2. Wait: Give the fuel pump a few minutes to prime and push the air out of the system.
3. Try starting: Attempt to start the engine.
4. Check the fuel pump relay (if necessary): If it still doesn't start, you might check the fuel pump relay (location varies by model, consult your owner's manual). However, this is less likely to be the problem after just running out of gas.
5. Professional help: If it still doesn't work after a reasonable amount of time and troubleshooting, it's time to consult a mechanic.
In short, there's no reset button. The problem is likely related to air in the lines and not a need for a reset.
