W126 (420 SEL) fuel-pump relay location

[randy]

Hello, I think my relay has failed (no fuel to engine; pour petrol in, it tries to run). Where is the relay and how can I identify it?
Regards, Randy

It's just in front of and to the right of the brake booster - small black box with words '8-zyl' and 'Kickdown' written on it.

126 Fuel Pump relay 1989 300SE

Hi Can you please help me. I have a starting problem with my 1989 300SE. The fuel pump runs when you start the car. I observed it while my wife cranks the car.

Could it be teh fuel pump relay. How do I test if this is bad?

Thank you for any advice.
