1995 E320 Starting Problem
I have a 1995 E320, and all of a sudden it wont start. It won't even turn over. I turn the key and nothing. I checked the battery and it still has juice left in it. The dummy lights come on when I turn the key, but thats it. The starter does not engage at all. Like I sid this happened all of a sudden with no warning. Any ideas of what it could be, and where should I start looking. Thanks

Try starting it in neutral in case you have a bad neutral safety switch.
|
I tried starting it in Neutral, drive, park, and nothing. The starter does not even engage. SI there a fuse or relay I should be looking at. I looked at the fuses under the hood, and they are all good.

Replace fuse #5.
That is K38 relay feed. ftp://members.aol.com/ajdalton7/K38.jpg If that does not work, jumper bat 12v pos to center terminal of the 3 wire connector on the firewall between the engine and booster area..just to the left of brake reservoir.. [ X/27-v/wht on schematic] ..that is starter sol feed and will test starter circuit . Report findings......... |
ptm6295, how old is the battery in your 1995 E320? When a battery fails in a MB typically there is no warning ... the car won't start even though the courtesy lights and dash lights work.
|
On my 2000 E320 Wagon I thought the battery had lots of life left but the E class seems to need a lot of juice to get the starter to engage.
New factory batteries are only about $125 and would be the first place I would look. |
I am going to replace the battery, I do not know how old it is, it came with the car when I bought it a year ago. I will also replace fuse #5. Are you talking about the #5 stick fuse in the fuse box under the hood, or are you talking about a relay somewhere else? Thanks
|
I replaced the battery with a brand new one, and replaced fuse #5 under the hood, and still the same thing. Dummy lights and buzzer come on, but starter does not engage at all.
|
You tried in N using the new battery too, right?
Arthur had another test for you to do in his post.... |
Can anybody give additional info about the location of X27.. ie a pic or few more details..? I think that would be helpful here.
|
Maybe this will help:

Ok, first off thanks to everyone for the great advice. OK, I jumped the 12+ terminal to the middle terminal of that plug, and the starter turned over. Since that worked what is the next step, and what is most likely the problem? Thanks again
|
Read the last link I posted... then search for "X27" using the search function for this site. There are about 10 threads there that are pretty much all covering what you need to do next.
|
First thing tomorrow I will pull the cluster and jump the x38 relay. I will let you know what happens after that.

OK....next test: Test for 12v at V/GN at the X49/2 plug [ terminal #3] with ignition sw in Start position. That verifies K38 contact set circuit [ just above the gas pedal] ..or, you can do the same 12v bat jumper as you did on x27, but to that point at X49/2 for starter activation in N or P. If starter works with jumper power to there , k38 circuit is open. If it does not, then you have a bad NSS. I would also do a 12v test on both sides of fuse 5 to ground w/test lamp before checking k38 relay circuit, just for power verification for relay coil. |
