1990 240 auto, 90,000 miles. bought the car 4 months ago and drove 3,000 miles with it. Car was starting fine except I noticed a few times I would turn the key and nothing would happen except all the lights in the instrument panel would come on as well as the headlight (just like a normal start). It seldom happened. Usually I would turn the key off and on and then it would start. But it happened like once a month. Yesterday I drove 4 hours on highway, then stop 1 1/2 hour and when I tried to start it, it was not working. I simply turned the key in the off position and then turned the key to start it and it worked. Today I drove a few miles and turned off the engine. When I started a few minutes later, at first it didn't want to start. I tried and tried, by rotating the key from the off position to the start position and then it did start. As soon as I arrived home (a few miles), I stop the car and then tried to start it again and it did not start. I waited a few hours and tried again and it didn't start. There is nothing wrong with the fuses, nor the battery. If you could make a suggestion as to where I should look, I would be extremely grateful. Thanks in advance. |

Wiggle the shifter, assuming this is an automatic, then try to start it. Yes, it is an auto, but wiggling the shifter as well moving it in all the gears and then trying does not help. Is there a solenoid or something like that? My friend who had a early 90's Audi told me that she had teh same problem and after the dealer changed tehstarter, etc. they found out it was a solenoid (or a name similar to that). Except it cost her $700 before they find out. I would appreciate all suggestions as to what to try next. |

Its not so common these days, but yes it could be a sticky solenoid or dry engaging fork the big round thing on the side of the starter, its a big relay and drives the gear to the engine. Standard practice is light tapping with a hammer on the solenoid or use the handle of the hammer. Don't hit it too hard with the metal end of the hammer, you might dent the casing. Also watch out you don't hit or short the live feed. I tried the best I could what you suggested, but it doesn't seem to work. Or I'm incompetent, lol! At the garage, should I tell them to change the solenoid first or go with the starter if this is what they wish to change? Thanks. |

The starter is only held in normally by 2 large bolts into the block/bell housing and a small nut for the big power feed. If you can remove these its the hardest part. Disconnect the battery first to avoid shorting to the chassis. Starters are also easy to fix, you can repair almost any problem at least temporarily, unless there is a mechanical breakage. Sticky solenoids can be greased, worn brushes can be cleaned up and the brush surfaces rubbed down with wet/dry, new brushes cost nothing and can be resoldered in, bushes can be replaced with basic tools. -- Tony |
