Mercedes Maintenance Journal

Real Men can Fix Mercedes!



November 12, 2015

Discover my Mercedes still has original tools kits and radio works.  Trying to find out if the radio unit will lock up when battery is disconnected.  Got spare tire out, it's bald, and loosed front lug nuts on flat tire.  Check air pressure of spare tire and got my battery charger back from landlord.

Nov 13

Charge battery.  Change front tire, oil threads.  Looks like front wheel bearing have been service.  Took pictures of everything, there is going to be some rust restoration.  Found out there is no air filter and one of the fuses is blown( thee rest look good).  Added coolant and oil before trying to start.  NO LUCK!
Still will not start, going to check fuel to engine, check fuel pump, and change fuel filter. Started to clean engine bay, I change the flat tire, and I am charging battery.

Remove battery and checked relays.  The Overload Voltage relay needs replace.
Has 2 fuel pump relays;
Plan to replace 2 fuel pumps, fuel filter, and fuel accumulator;

Received 10 inches of snow, Mercedes repair is on hold.  Researching parts and budget.

  Snow melted.
Loosen fuel line to fuel distributor, going to check if fuel pumps work.  Rub oil inside of back tire rim and brake rotor.

Nov 26
It Feels Good
Driver's window need fixed, doesn't go up or down
 Might need to change window switch

The radio still works even after the battery was disconnected

Nov 29
Use jumper wire on fuel pump relay socket at #30 & 87, got fuel deliver to fuel distributor, tried to start - no  fire :(  Pull #1 spark-plug, look bad).  Plan on replacing all spark-plugs, distributor cap and rotor.  Also plan to  change fuel filter and add new gasoline.
Should order new fuel pump relay and Over load relay, and plastic relay/ECU cover(p/n #124 626 1630).

Update:  clean corrosion around Voltage Overload Relay and fuel pump relay contacts, this amazing care started right up!
