Beautiful day, I thought I would take the bike out for a ride. Moved the car 1984 300D, it started fine with one rotation. Got back from the ride to move it back behind the trialer, it started but rough then it shut off. attempted to start it nothing, it just turn over. so I did the following:

Disconnected the #1 injector fuel line, had wife crank it over no fuel came out. Fuel is supposed to come when the engine is being turn over right?

Both fuel filters are new, standard protocol after buyin a use car. Change everything, oil/filer, trans fluid, air filter and fuel filters.

Where can I start to isolate the lack of fuel?

What else can I check to verify fuel is not making it to the injectors?

This car has 76K original, but sat for at least 12 yrs. The reason I say that because the last yr it was registered was 2000 as indicated on the tags that were on it before I picked it up.

It was running great, drove it 300 miles already. Thanks in advance.
