Question New member with a vacuum question

1984 300 D Turbo I just inherited the car, it has some vacuum issues.
1) door locks
2) won't turn off with key
when I started testing the pump it seems to work fine 24hg at pump, 22hg at booster. however the pump will sometimes not work at all, and than come back on. I loose the brake booster and other things when when it goes out, but the locks and ignition don't work at all, how much vacuum should there be down the lines for these functions? I'm new to both diesel and MB

Try the search function vacumn cut off should have been discussed before. I am not a diesel owner so can't help there other than to let you know you can manually cut it off from under the hood.

On the point of starting car after 4 years none starting, did you flush the fuel tank and clean the strainer, replace the fuel filters, toss the oil diesel?
