I need alittle help with a fuel problem on my 86 560SEL. While driving the engine just stopped. After 5 minutes it starts OK. This happened several times over 3 or 4 days. The last time it will not start. I wish I had a manual so I could test a few things, but I don't. I disconnected the fuel line at the fuel distributor and tried starting and didn't receive any fuel from the pumps. I looks like pumps are not getting power. I would appreciate any suggestions or tests. Thanks - DAS
