I have a 1993 190e 2.6 that's been sitting for seven years it doesn't start and has a half tank old gas any ideas
yes...get rid of all the old gas..put an ounce of transmissin fluid in each cylinder and withe the plugs out rotate the engine by hand back and forth several times..pug new plugsand gas and a battery check water and try and start it .
After you do what Kelly suggested, check that you are getting fire to the plugs.
Have it towed to your mechanic and be prepared for a major tuneup as well as dropping the gas tank that may run $1000+; don't let cars sit - it gets very expensive.
