check for the vacuum line in the back of the injector pump. i believe
it’s brown colored, comes through the firewall from the ignition, runs
alongside the oil filter housing (easy to knock off when doing oil
changes) and goes into the back part (toward firewall) of the IP. If
it was knocked off, the car won’t shut off anymore. Just stick it back
in. If it’s a more chronic problem, you may need to repair vacuum
lines or even pump

Not sure how the system works on this vintage, but on my 1980 300SD
the vacuum line splits off from the main vacuum hose coming from the
vac pump on the engine, runs through the firewall to the ignition
switch, which contains a vacuum valve actuated by turning the key.
Then a line runs from there to the shutoff bellows on the injection
pump.

On my car, I had 2 vac lines fail, both were broken right where they
go through the grommet in the firewall. One was the engine shutoff,
the other worked the doors. When I worked them a bit by hand, they
just broker off.
