35D wont start - Glow Plug pre-heat issue?
 

This morning i tried to start as always and it wont fire up.
Its 45 outside and i get the coil symbol for few seconds, message saying pre heating please wait then it goes away but nothing happens.
When i hit the start button again it turns off from ACC mode.

I could not get it started , no matter what combination i tried. Is there a trick to this? First time seeing this message.

Also my TPM light is on, tire is fine, maybe little low so added air but cant reset until the car is driving, not sure if that would cause it to not start?

No codes present, battery seems fine. Nothing was left on over night.

HAAAALP??

Does the engine turn over vigorously? Is the battery fat?

Some modern automotive diesels do not even energize the glow plugs to start until temperatures are less than 40°F. Further, some modern diesels require a minimum starting rpm before fuel will be injected to start.

No it doesn't turn over, it acts like you are just toggling between ACC mode and off by pressing the start button, even though i have my foot on the brake trying to start it.

If the GP's are indeed lit, that's a significant drain on a battery, maybe too much. What reason is there to believe that the battery is fine?

Buy a new smart-charger (that can recognize an AGM battery) and charge for twenty-four hours.

Check your ground cable between engine and chassis.
To diagnose ground fault,try this simple test.
Use a jumper cable and hook one end to any metal point on the engine (non painted surface ) and other end to any metal point(non painted surface like front bar on the top of radiator fan) on the chassis and try to start if that makes any difference.

Question:

I remember reading about some starter relay not working when cold outside, but I'm not sure it applies to diesel as well... Anyone?

I tried jumping it, battery showed 11.6v prior to hooking it to the other car, during the jump it showed 13.6v bit after waiting for few minutes it still doesn't crank over and i still get the pre heating message. I have all 6 GP codes and 6 GP circuit codes. Erased and tried again but no change.
Could it be the GP control unit? It was working fine prior to yesterday. No start or rough idle issue.

I suggested you to do jumper cable test .Did you try that???

All 6 glow plug error points to ground cable issue.Try that test.

I will try that now. where is the ground cable located so i can check it?

Ground cable is kind of hard to access as it's hidden somewhere in the wheel well.but to make sure it's ground issue( which looks like), take a jumper cable and use just one wire of the cable(either red or black).Let's say you use black.So connect one end of black to any metal surface on engine which is non painted.and connect other end to metal point on chassis like shiny bar just on the top of radiator fan.Leave both ends of red wire alone.and try to start the engine.
Let me know if you want more description.
