Why generators fail when you need them
A portable generator can sit for months and then be needed all at once during a storm. Fuel left in the tank and carburetor breaks down while it waits. That’s the most common reason a generator won’t start, and it’s why getting one checked ahead of storm season is worth it.
Common generator engine problems
- Won’t start. Stale fuel, a closed fuel valve, low oil triggering the shutdown sensor, a fouled plug, or a dead starter battery.
- Starts and then stalls. Often fuel delivery or the low-oil sensor.
- Surges or runs unevenly. Frequently a carburetor issue from old fuel.
- Leaks fuel or oil. Stop using it and have it looked at.

Generator safety
Carbon monoxide can kill within minutes.
- Never run a generator indoors, in a garage (even with the door open), basement, or shed.
- Run it outside, far from doors, windows, and vents, with the exhaust pointed away from the house. Follow your manual’s distance guidance.
- Keep battery-powered CO alarms working in your home.
- Never plug a generator into a wall outlet. Backfeeding can kill utility workers and damage your wiring. Home connections need a transfer switch installed by a licensed electrician.
- Let it cool before refueling.
Before the next outage
Fresh fuel or properly stabilized fuel, the oil checked, and a test run are the basics. If it doesn’t pass the test run, call or text (734) 400-0790 so it’s sorted out before a storm.
