1990 560 sel will not start. Not getting fuel to engine

I have a 1990 560 sel. Vehicle wil not start now. Not getting fuel to engine. I pour gas into intake and it will run. Fuel pumps or relay fuse need replacing??

Hi gregburg1,

This could be your fuel pump, fuel filter or fuel regulator. I would also check (just to be sure) that you don't have any "crimped" fuel lines between the tank and the fuel rail.

Good luck!

Definitely sounds like the fuel pump or relay. Unless you have very high mileage or you have been putting crapy
gas in it, i would put my money on the relay. Either way it is not to hard to fix.
