My car suddenly started to have internitent starting problem. Battery
has had plenty of cranking power but motor either starts with lots of
difficulty or shut down while stopping at red lights. Finally it
didn't start at all. It is towed to Benz dealer. From all previous
messages, my thought was on fuel line (filter, pump, relay) but
mechanic says they are all ok and he also gets spark but no starting.
He finally called and said he thinks it may be a control box that
contorls ignition. I have no part number but he said the part runs
close to $1000 (US)! Any suggestion what that part would be and any
other thoughts. Thanks a million. Adam

Change the Over Voltage Relay

Thanks. Can you tell me how over volt. relay goes bad? I used one full
tank of midgrade gasoline (89 US octane) few weeks before this
happened. Is there any relations? Thanks

My 300te was acting this way recently but main clue was that when it quit,
it had no spark. The control unit was shutting down when the sensor reading
was bad. Then sometimes it decided things were OK and would crank up. Here
is the story and a simple way to test:

btw, if it is indeed a bad control unit you can find used ones at salvage
yards and ebay for much less than that.

OVP is common fault .. the problem is from bad solder joints in relay..
Some guys resolder ... I change them b/c there has been a part
improvement/upgrade,,,
