|  Hard Starting 300E 
			
			Everytime I go to start my car after the cars been "resting" it always takes forever to start. I turn the key, it cranks and cranks and cranks and when i think i got it started, it stalls.  Recently it's been doing it occationally after it's jus been started.  So what helps a bit is reving it while im starting, but still occationally stalls.  I had some work on it a few weeks ago and my mechanic said it needed some new spark plug wires, now i didn't want to have him do it cause i was gonna have to pay much more to get it done, so i figured i'd just do it once i got around to it, which i havn't yet.  Would that effect my starting that much? Also would worn Spark plugs do all this? Im going to replace these things with in the month.  Also, would fuel injecters have a part in this?  Once our school shop become usable (under construction), im going to be doing all this work then. Thanks in Advance |

			Did you ever solve this? I've got a hard starting problem with my 92 300E, too.

			If the ignition system is not in top shape, it could be one of the causes of your problem. Other possible causes: Fuel accumulator, fuel pump, fuel filter, cold start valve (below a certain temperature). Been there, done that. Good luck jackD |

				for Chris17H re your starting and stopping 300E
			 
			
			One day I tried to start my 86 300E and it started then died. This happened several times in succession. I called MB and they replaced the Fuel Accumulator. It has been starting fine and running well since. Might be your problem. Al |

			It turned out the coil was the culprit. Replaced it and everything's fine! Thanks for the response. |

			The starting problem existed only in cooler and/or wet weather. My guess was that fuel delivery wasn't the problem, otherwise the problem would probably have been more consistent, despite the weather.  I didn't really know it was the coil, as I don't have my own diagnostic equipment, but I took a guess and figured I'd start with the easiest-to-deal-with, most common problems. The car has over 150,000 on it and the coil was the original part. I found a guy who would replace it for $110, parts/labor, so I figured what the heck. The coils tend to go on these cars after a certain time anyway. I did also replace the overvoltage protection relay previous to the coil, but that wasn't the problem. But i've heard that sometimes that can be the culprit, too. At least now I know those two parts are OK for another 100,000K or so.

			Is replacing a coil a DIY type job?  Is the coil ever replaced at one of the major services, i.e. 120,000 miles? Thanks, glenmore 1991 300CE |

			Replacing the coil is definitely a DIY job -- should take no more than 20 minutes or so. You can find the part at wholesale pricing of just over $100 or so. I don't believe the coil is automatically replaced at any servicing. I checked back on that on the description of the 120,000 service, which I took my car in for, and nothing about the coil is mentioned. Remember, I drive a '92 300E: it has one coil. I believe other models may have more, or even no coils? |
