Left side of engine under the intake manifold.
Fuel Pump Relay.
First take a look if the ABS light is on, if yes, check your OVP relay.
A Mercedes 190e doesn't have a carburetor. They are fuel injected.
It is directly behind the battery. You have to remove a black plastic cover that is directly under the windshield to expose the relay. Thanks
If the ignition shuts down, however you can still crank the engine. This issue could be fuel or ignition related. Fuel Pump Relay failing. Overload Relay failing. Fuel Pump failing. Distributor Cap failing. Distributor Rotor failing. Ignition Coil failing. Ignition Wire Set failing. Reference Sensor failing.
oil filter on a Mercedes 190E 1986 is in the back of engine
crank position sensor is between oil filter and starter, follow wire from module
There is none, just relays! 2 relays and a relay with a 10amp fuse behind the battery.
