On a 1991 Mercedes 190E, the ignition or starter relay is typically located in the engine compartment, near the battery, on the driver's side. It may be found in a relay box or fuse box that contains various relays and fuses. To locate it more precisely, consult the vehicle's service manual or check for a diagram on the underside of the fuse box cover.
To bypass the ignition on a 1993 Mercedes 190E, you typically need to connect the battery power wire to the starter wire. This is usually done by locating the ignition switch wiring harness and identifying the positive battery wire (usually red) and the starter wire (often yellow or brown). However, this method is not recommended as it can lead to electrical issues or damage, and it may be better to address the underlying ignition problem directly. Always consult a professional mechanic for assistance.

Consult the vehicle's service manual for the exact location and identification of the relay to ensure proper handling.
The ABS relay on a 1990 Mercedes 190E is located in the engine compartment, specifically in the relay box near the battery. To access it, you'll need to remove the cover of the relay box, where the relays are arranged in a grid. The ABS relay is typically labeled, making it easier to identify. Always refer to the vehicle's service manual for precise details and diagrams.
First take a look if the ABS light is on, if yes, check your OVP relay.
Fuel Pump Relay.
To test the fuel pump relay in a Mercedes 190E, first locate the relay in the fuse box. Use a multimeter to check for continuity by connecting the probes to the relay terminals; it should show continuity when energized. Alternatively, you can swap the relay with a similar one in the box to see if the fuel pump operates. If there's still no fuel delivery, the issue may lie elsewhere in the fuel system.
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
A Mercedes 190e doesn't have a carburetor. They are fuel injected.
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.
There is none, just relays! 2 relays and a relay with a 10amp fuse behind the battery.
