I have a 1974 Mercedes 450SLC that will not start due to lack of fuel delivery. When I turn the key, the fuel pump does not hum. The car does run if I pour gas into the throttle body. Can you tell me where the fuel control relay is located? Thanks.

 

Optional Information:
Pre-1981 Mercedes-Benz 1974 450SLC 4.5 V8

Already Tried:
