My ML is having an intermittent no start. It stopped about 3 weeks ago but restarted. I drove it a couple weeks but felt at times a little hesitation. Two days ago is stopped again this time i couldn't restart it..

1. when I turned the key to restart – absolutely nothing

2. I removed the key, replaced and tried again… nothing… no cranking… nothing.

3. I had no power windows and no power door locks. Had radio.

4. I did not have the usual array of dash board lights……. Just 2

5. the car was towed to the shop and of course has started ever since! No codes off the scanner.

6. After reading the forum I found a guy with a similar sounding problem suggested fix was circuit 15 relay. My tech says no because of the absolute lack of anything when I tried to started it immediately after the failure. He says if it were a relay it would at least turn over. Same with a crank position sensor... it would at least crank but I had nothing.



Any ideas would be appreciated. I’m kind of ready to just have him start throwing parts in even if we don’t have a clear diagnosis. I don’t want to be without the car for however long it takes for it to fail for him.
thanks

The circuit 15 relay is the MOST likely issue.

Replaced the circuit 15 relay and the electrical side of ignition. ran fine for a week. several days ago with car running fan stopped working and power windows would not work. turned fan on and off a couple times and it started working again, also windows.
Yesterday would not start, no cranking just silent. no power windows. after several tries it started.
any ideas?

AAM fixed the problem. thanks very much to MBDOC for the help.
