Msnapper Posted June 14, 2016 Report Share Posted June 14, 2016 Recently I've had issues with the car cranking but not starting. I've changed the fuel pump controller and car ran ok for about a month now it's doing same thing again. No codes when scanned,and no check engine lights Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted June 14, 2016 Report Share Posted June 14, 2016 (edited) How many miles on your Edge? Does the fuel pump prime with the key in the ON position (but not started)? Checked fuel pressure at idle, before start (after sitting overnight), and after shutoff (15, 30, 60 min after)? And of course, since the 2011 brought many electrical gremlins, condition of battery/alternator? Any problems with the CD skipping, or with the shifter not shifting properly?

Msnapper Posted June 14, 2016 Author Report Share Posted June 14, 2016 127k I don't think it has a test port on the rail to check pressure. I've tryed to listen for pump can't hear it and also disconnected it at Rail and cranked engine,no fuel came out so I assume pumps not priming Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted June 14, 2016 Report Share Posted June 14, 2016 The fuel pump relay COULD be bad, it is commonly pulled when you want to crank the engine without the fuel system firing. Seems like what you are experiencing here. What is the cranking RPM? Did the Edge suddenly stop responding on previous trips? I assume no codes available ... The electronic throttle body could be suspect. Yeah, you have to get an adapter to test the fuel pressure mechanically. They killed the Schrader valve feature in 2010, apparently. I mean why should they make this easy, right? The easiest thing to suspect is fuel pump, or bad wiring between the fuel pump and the fuse box/control module somewhere. Maybe the connectors are corroded and need cleaning/replacement. Quote Link to comment Share on other sites More sharing options...
Msnapper Posted June 14, 2016 Author Report Share Posted June 14, 2016 I swapped relays and change fuse. Is there a filter in the system. Is the inertia switch that shuts off pump in accident contained in fuel pump control module? Quote Link to comment Share on other sites More sharing options...
Msnapper Posted June 14, 2016 Author Report Share Posted June 14, 2016 Battery voltage was 13.5 and while I don't have a tach, it doesn't seem slow cranking Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted June 14, 2016 Report Share Posted June 14, 2016 (edited) Isn't the tach digital in the 2011? The cranking should be between 150 & 350 rpm. The FSM doesn't show where the inertia switch function is located on the 2011 (or at least I am not able to find it). On some models, it is a function of the Restraints Control Module (RCM), but it is not showing there either. When did you take the voltage reading of the battery? Everything off, or on a previous run where the Edge was running well, or ...? Should be around 12.6V with everything off, and 13.5-14.5V with the engine running (idle-2,500 rpm).

Msnapper Posted June 14, 2016 Author Report Share Posted June 14, 2016 13.5 was voltage the previous time it happened after it was running. Quote Link to comment Share on other sites More sharing options...
Msnapper Posted June 14, 2016 Author Report Share Posted June 14, 2016 I've never noticed if tach displays when cranking . I'll check tonight 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted June 14, 2016 Report Share Posted June 14, 2016 I found the inertial switch listed in the Ford catalog for 2007-10, but nothing for 2011+, which leads me to believe its' function is integrated into some module. And yet, the 2012 (not 2011) FSM has a line in there stating exactly this: "Verify the inertia fuel shutoff (IFS) switch is set (button pushed in). Refer to the Owner's Literature for location." Of course, no mention of where this switch might be in the owner's manual either. Fun times. Quote Link to comment Share on other sites More sharing options...
Msnapper Posted June 14, 2016 Author Report Share Posted June 14, 2016 Yeah 11 owners manual Says to reset go key off to on 3 cycles 2 Quote Link to comment Share on other sites More sharing options...
