Car starts but won't run. There is no gas pressure at the throttle body.

(1992 Mercedes-Benz 300SL)
When you spray gas directly into the carb, it will keep running. there is no pressure there.
How long have you had this problem? Just got the car.

Hello,
Start by checking the fuse and relay for the fuel pump. Once done, make sure you hear the fuel pump running, and see that it is producing pressure by testing the fuel pressure with a fuel pressure gauge. (can get them on loan from parts stores sometimes).

This is likely going to be a fuel pump or fuel filter issue, and those may be the same part.
