The fuel pump is not getting power, it will start if I pour gas in the carborator. What could keep the fuel pump from getting power?

Fuel pump relay, it's behind the battery, a black box which will have "6 zyl" printed on it, and an RPM, which is the safety cutout RPM. There is a nearly identical one near it which says "Klima" on it, that's not it, that's for the AC compressor. I can tell you how to do a temporary bypass of it, so you know it's the relay or not. Others can also tell you how to possibly repair the relay, if you are so inclined (need to solder stuff).
NOTE the engine is injected, that is NOT a carburetor you are pouring gas in to.

Gilly can you please tell me how to bypass the fuel pump relay to make sure that is my problem?

a carb? really...where do you live that has 87 Benzes with carbs? interesting

That's what I was thinking, MB went carb-less loooong before the M103 ....I suppose it would run if you had gas fumes in the intake though....

Fuel pump relay needs replacement.
