To clarify, it's a diesel engine - the OM603 - so it doesn't have spark plugs. Im sure people here want to help but I also need them to be flexible and understand that im in morocco and the VIN number on the front of the car really doesn't mean anything. I checked with the VIN sites and got two different answers. It's a W126 which might have started life as a 500 SE but, according to one VIN website, came out of hte factory in dec 1984 as a SDL five cylinder diesel automatic.
Would it make any difference to this specific problem if it were orignally a 500 SE even though i have a diesel engine in it?
I can assure you that i'm not confusing anyone by "intent". Can't think how you would think such a thing. I have a W126 long wheelbase car which it seems has gone through many identity overhauls. Im always grateful for any advice on my frankenstein jallopy.
Your advice is excellent. Yes, i should see if there is continuity between the ground in the plug and the ground on the steering column. But any idea which number terminal in that plug is the ground? Thanks

If you have continuity there then pull the sending wire off the sending unit at the fuel tank and check that ground.
I'm really confused that you think your car is a DSL [sic] but later, within the same post change your mind to thinking it's a SE. An SDL, as properly designated is the longer body w126 with a diesel engine. I'm not sure MB made an SDL in 1979.
Nevertheless, I'd say your problem is at the sending unit. Either a ground there or the sending unit needs to be removed and cleaned.
Have you considered which fuel to use or read the designation on the trunk of the car? I think you are confusing most of the good folks on this forum either by intent or from inexperience. Either way we need to know which engine is in this car if you expect the more seasoned veterans here to try and help you. I'm not trying to be harsh but you gotta figure out some of this stuff if you expect much help.
Does it have spark plugs or can you take a photo or draw a picture of the engine, anything?
