Long cold crank - 560SEL
This just started during the past week. When cold, sitting for at least 8 hours, the first start takes a good 5-10 second crank before catching. A quick search shows mostly hot start problems, with many suggesting the fuel accummulator or fuel pump relay as the culprit.
On warm/hot starts it catches fast, fast enough you only have to tap the key. It would appear my symptoms are 180* out from everyone else's. Any suggestions on where to start, fuel pump relay or accummulator or cold start valve?
I only have a limited time to sort this out before heading off to the Great White North, where I expect many cold starts.
