Help! ML350 Won't Start
 

Hello, I just attempted starting my car, and it won't start.
When I turn the key for ignition, engine attempts to start, but it is "stuck" cranking and does not start.
I did leave the car for about 2 weeks, so thought it may be the battery issue, but I am unsure since I've never encountered this kind of behavior before.

Dashboard Lights that are on:
Triangle with exclamation mark
Triangle with car
LIM (ABS)
SRS
Check Engine

UPDATE
Had it jumped using a friend's car.
It did start after a few "coughs" with all the dashlight warnings going away except for the Check Engine light. Check Engine light blinked a few times before it became permanent.
I was able to feel that something was wrong with the engine (weird vibrations).

I let the car run a few min, then turned it off, to see if the check engine light would persist if I restarted it.

Strangely, problem went away when car was restarted - no check engine lights or the weird vibrations.

Search around the forum. Have heard of this a few times before and it usually points to the famous cam (or crankshaft) position sensor issue.

Check your gas cap maybe?

Never mind the above. I just saw you updated your post.
