Hi Guys n Gals, im a newbie on here. hope someone can shed some light on my problem, im in the United Kindom and own a 2006 diesel grand cherokee jeep, its a fantastic car i have owned for one year, its regularly serviced by dealer, its only done 95k, last winter first frosty morning would not startup, turns over nice and quickly but would not fire up, called out recovery, they checked battery etc, got it started using easy start spray down air intake, they said glow plugs could be problem !!!! since then i have had glow plugs done,a full service and changed 3 relays,changed a faulty hose on fuel filter, it was great for six to 8 months , now cold weather is starting , 3 times it has not started , only way to get it started is easy start down air intake when cold. Once it has been started it starts fine all day.?????? your thoughts please guys, the dealer doesnt seem to be able to sort it and i cant afford to keep going there. thanks in advance for any help or ideas, i absolutely love the car but this is a PROBLEM...

You didn't mention what the temperature is- but it does sound like a glow-plug problem since it starts with some help. Maybe have them confirm power is getting to the plugs?

FYI - I was able to start my vehicle this morning with temperatures around 0 degrees with wind chill approximately negative twenty or below. Diesel fuel can gel and using a "winter blend" is what prevents this from happening.

Perhaps your fuel "thickens" enough at night to need help getting started and warms enough during the day to work fine. If all the attempts with the mechanic fail, look into a fuel additive that prevents the diesel fuel from gelling or make sure the gas station supplies a winter blend of fuel.

Keep us posted when you get this resolved.

I had a 2007 CRD here in the UK that did the same starting issue in cold temperatures so i changed all glow plugs but problem still occured. Has your dealer changed the glow plug control module?? that was the problem with mine.
I purchased a new module from a merc dealer for i think £120 and fitted myself and no further problems.
