My car won't start after sitting for weeks. What now?
The most likely cause is a drained battery, since modern cars draw a small amount of power even when off. Try a jump start or a battery charger first. If it cranks but won't start, old fuel or a fuel pump problem is likely. Once it runs, check tire pressures, expect some brake noise from surface rust, and look under the hood for chewed wires or nests, which are common in parked cars.
Getting it running
- Charge or jump the battery. If it won't hold a charge afterward, it may be permanently damaged by sitting flat.
- Listen when you turn the key to "on" without starting. You should hear the fuel pump hum for a couple of seconds.
- If it cranks but won't fire, old fuel, a weak fuel pump or a clogged filter are the common causes.
Before you drive it
- Tires: check pressures; they lose air while sitting and can develop flat spots
- Brakes: rotors rust; light grinding for the first few stops is normal, but a car that pulls or grinds constantly needs a look
- Under the hood: look for nests, droppings or chewed wiring
- Fluids: check oil and coolant levels, and look for fresh puddles
- Wipers, lights and horn
Storing a car the right way
Use a battery maintainer, fill the tank and add fuel stabilizer, inflate the tires to the door-jamb pressure, and start and drive it at least every few weeks if you can. For a classic that's been parked for years, a full recommissioning, with fresh fluids and new rubber parts where needed, is safer than just starting it. Classic car service
From drivers who came to us
I haven't used my Ford during the COVID period and for some reason it would not start… There was no need to have my guard up for any upsell.
I have an 1980 Datsun-ZX that I've had since it was new, and it's my only car. Finding skilled professionals who can work on this vehicle is not that easy. These guys understand, respect, and love an old classic like this one.

More questions
How long can a car sit before the battery dies?
Many modern cars can drain a healthy battery in two to four weeks of sitting. Older batteries die sooner. A battery maintainer keeps it charged.
Does gas go bad?
Gasoline starts to degrade after a few months, faster in a partly empty tank. Fuel stabilizer helps for long storage.
Should I change the oil if the car hasn't been driven?
Most manufacturers specify an oil change by time as well as miles, often once a year, because oil degrades and collects moisture even when parked.
