| Starting problem SOLVED!!!!!!!!!!!!!!!!!!! Okay, so here were my symptoms: (someone please add this to a sticky somewhere - wolfgang you may want to add to your site: A) The car would have a hard time starting when left off for more than a few hours. B) I looked for the little red LED to flash (by the Low Range switch) when I turned the key C) If I left the key in position 2 for more than 30 seconds, and then cranked, she would start right away. What that simple procedure did was immediately rule out: 1. DAS (Driver authorization systems) 2. Battery 3. Crank Shaft Position sensor. So the only thing left was the fuel delivery system. As Wolfgang and Rudeney pointed out - the most probable cause was the check valve integrated into the fuel filter unable to maintain fuel pressure after I leave the car off for several hours. When I turned the key to position 2 it activated the fuel pump and re pressurized the rails. 2 tankfuls of Techron DID not help.... So I went to my trusty dealer and of course because my ML is a 1999, I cannot just change the fuel filter. I have to update the pump and the lines. Total cost parts and labor was around $1030 - VERY reasonable in my opinion, and best of all SHE'S ALL FIXED!!!!! and STARTS LIKE A DREAM. Here are some advantages of having done this fix: A) She pulls VERY STRONGLY off the line, and there is ZERO delay in passing from 55mph to 90mph - just keeps PULLING AND PULLING  B) ANY hint of a slight rumble at idle after a hard run is GONE C) Fuel economy is up. Thanks everyone! | ||
