I have an '88 560SEC that had been sitting for 11 years and won't stay running. With only 109,000 miles on it, what could be wrong? New fuel filter, pumps and relay.

11 year old gas isn't nice (neither are 11 year old tires,belts,hoses) Siphon out the old,put in full tank of high test and some Sea Foam or Wynnes or what ever brand you like. Check air filter vacuum lines,etc. And don't be running around in it until you checked out all the other 11 year old oil,filter,tranny,coolant. Peek at the brakes and I can not imagine the rubber is any good.
