Have a 67 230SL  starter is turnig over but appears not to be getting gas.  Just turns over doesnt seem to be getting gas.  any trouble shooting recommendations.

How do you know it is not getting gas?  Can you hear the pump when your turn the ignition switch to position 1?  If so how long do you run the pump before turning on the starter?  How long has it been sitting?  Need a bit more information to do a proper diagnosis.  Do you have spark?

All good questions by Jordan.

I've read to check fuel, slightly loosen the fuel line where it connects to the #1 injector.  Maybe put a rag around it to prevent spray.  See if fuel comes out when trying to start.  Tighten and go to the next injector.  Best done with a helper turning the key while you're watching the fuel line.  Don't wear down your battery, do wear safety glasses, and no smoking!

You asked for a fuel delivery test and I suggest one.  Maybe someone else can recommend a better test?

Do you work on your own car very much?  Just wondering how comfortable you are with carrying out recommendations.  Some people here are new and mechanically inexperienced, some are experienced and competent, and some are basically master mechanics.  How would you describe yourself?

Side question: I checked your previous posts and I see you posted questions about drum brake parts in August '20, March '21, and April '22.  Did you ever get the parts and fix the brakes?

Perhaps the simplest test would be to test the fuel flow volume at the return line of the fuel pump.  Run hose to a container and turn the key to first position.  The flow should be 1 liter per 15 seconds.

That is a great test for many aspects of the fuel system and should be done first.  Doesn't specifically test delivery at the injectors, so if the first test passes then I'd recommend my test as a follow up.
