94 E320 no crank/start, no clicking - PeachParts Mercedes-Benz Forum

Have a 94 E320 with remote starter. When I try to start with key, panel lights come on, but no solenoid click, no crank. Same thing when trying to start with remote button. # 5 fuse replaced and OK. Battery fully charged and battery terminals clean and tight. Neutral safety switch is OK. Where do I start looking?

Did you try N ?

If YES , then is the ARM led ON at the console?

Did you try N ? Do you mean starting in neutral? Tried. Does not work.

If YES , then is the ARM led ON at the console? Do not know what you mean by ARM led at consol.

I have searched your other postings on this subject. I have jumped the + wire at the X27 plug in the inner firewall and she does crank.

I have also changed the 11, 12 and B fuses.

I have to go to work now...but my next step is to check the relay by the gas pedal inside the car(K38?)

Very good...I see you did your Homework by using the Archieves...I Salute you ..

OK , if you have crank from battery jumper to center terminal of X27 , then the next feed back in that power chain is K38. If you jumper that and it starts , that is the problem...next back from there is NSS . How do you know you have a good NSS ?

PS ..the reason I ask about the ARM led is b/c that is the Security System and if that is ON , you are armed and K38 will not allow start...That feed should be OFF and car unlocked ..Thta is what fuse #5 is for ...make sure that fuse is good ..they will fool you by just looking ..a test lamp on each side of the fuse will verify OK. K38 relay is most likely suspect at the moment.

OK Arthur...I jumped the V/GRN and V/W(in my case V coming to plug and V/W leaving) at the 4 prong-X49/2 plug next to gas pedal and she started. Is that good or bad? What next? Thank you VERY MUCH for your help.

OK
That is either NSS or K38..I will have to pull your schematic up a little latter to confirm..

... double check that fuse 5..both sides w/test lamp..they will fool you .

V/gr jumper to v/wt is NSS by-pass.
I do not know what you mean by V coming and v/wt going.

The plug ID # should be #3 for v/gn and #4 for v/wt.

If YES, that is NSS.

K38 is V and V/gn, but V comes from Ign sw.
