6.0 starst really hard if at all in winter.

[PowerFatty]

I have a stock 2006 lariat crew cab with the 6.0L in it. I got the truck in south Texas and i just moved to Maine and winter is coming its not my first cold winter with the truck but when it gets below 30 the truck is very hard to start. I keep it plugged in all winter but does not seem to help. The glow plug light comes on for 30sec to almost a minute before it will go off. It starts really hard when it does and just chugs until it goes into a higher idle. any idea on what it could be Ive heard of the glow plug resonator but i don't know what it does and how do i know my glow plugs are getting heat. if you have any idea please let me know thanks a lot, Matt

Geeez...i just responded on the other board, the same question on multiple boards is not necessary........usually.

Sent from my phone that somebody didn't help me get.

There really is no way to tell if they are generateing heat to the cylinder other than what you are seeing. If they test out electrically and still do not seem to be warming the cylinders I always suspect carbon build up on the electrode itself. The carbon acts as an insulater and absorbs the heat before it can get to the cylinder.

Remove the glow plugs and clean with a wire brush and emerycloth. Be carefull with the glow plug plugins and the electrode. The plugin is easy to break so is the electrode.

Has always worked for me.

Hard to imagine the block heater being plugged in would still allow the "Wait to Start" light to remain on that long. Not sure how cold you are getting over night, but an engine should be upwards of 90+ * (f) after an all night plug in. Do you have a monitor to read temps with? ECT EOT?

How about your FICM, tested it lately?

is the block heater really working. it may not be connected or have a damaged cord end.
i thought a burned out glowplug would at least set a code, I know on our chevies at work it sets the CEL.

then you must be the 2nd person ever to have heard of a GP resonator ?
