1980 Mercedes-Benz 300CD Early Model W123

1980 300CD Early Model W123 - Rare model you don't see these floating around much anymore.
Will not start, has been parked a few months due to new job and not driving it. Replaced fuel filter, possible fuel injection pump failure. Floor pans are rusted out, sunroof will not open, AC needs to recharged, will need body work, and paint.
These are the items I replaced since having it.New tires, shocks, brakes, calipers, linkage, steering arms, radio, vacuum lines, 4 way vacuum line, control arms both sides lower and upper, air cleaner mounting hardware, just changed oil and filters
New job so I do not have time to continue restoring it.happy bidding
