Engine ran rough then quit. Replaced fuel pump and fuel filter. Still will not start. Engine just turns over. I replaced the electronic ignition box a few months ago. There is a spark. Cannot drive car to local Merc. garage. Stuck.Can anyone help - please? Thanks, Henry

 

I am having the same problem you are having, changed both fuel pump and filter. Could you tell me what you did to get it started? Thanks

 

I had this problem and replaced the speed control relay under the dash on passenger side of vehicle. Before buying one check it to see if there are any loose connections or broken contact leads. I bought one and still had problems, I checked after the purchase and found out it had a broken contact. Hope this helps...
