1975 450SEL Request for Help to Get Running

[TwitchKitty]

I have volunteered to help a friend get a 1975 450SEL running after the car has been stored for awhile. I am not sure how long. I have not tried myself to make it run so I am after general systems information for now.

The data plate under the hood says it is a 276ci engine. By searching old threads and reading the scarce reference material I have on this car I think it is an M117.983 (4.5L). I think the body is a W116.033.

This is a V8. The injection is electronic and I think it is L-Jetronic. The distributor has ignition points.

Do you have any favorite threads you could point me to for this car? Searches came up pretty thin.

1) Is the ignition a straight points ignition with no interface to the controller?

2) Hydraulic lifters or solid? I think solid?

3) Electric fuel pump? Not in tank?

He told me that when he tried to start it the car would run for a few seconds and die. It may have run a few minutes one time. He says he thinks it has an ignition problem. We shall see.

Thanks if you can offer any insight or experience.

One thread that I read lamented the lack of these cars remaining on the road. I will be happy to help this one run again and document my experience here to possibly help the next person who tries.
