Cold start

[Corey whitehead]

I own a 2006 f-350 ford. After i bought the truck brand new, everyone told me it was of the worse ford I could buy and had lots problems. In six years my front end shimmied and had to clean out my egr valve. But now I have to warm it up for 20 minutes everyday before it will idle and drive without hesitation. I regularly change the oil and fuel filter will bad glow plugs cause this problem or was everyone just right and this truck just not built to last. Any suggestions?

I'm no diesel mechanic but this sounds to me like a glow plug issue. Just my 2 cents.

Check your FICM voltage. Is it getting harder to start and feel like it has a miss after it starts?

Mine does that on really cold mornings. Take about 4-5 sec to turnover and has a miss. Is that due to FICM voltage?

Wow 2 things in six years! Not bad is it!

Sure will

I second the FICM. Mine did that awhile back and I had to replace it. Everything was good to go after that.

From my research, it isn't as common for the GPM (glow plug module) to go out on a 6.0 as it is for the GPR (glow plug relay) to go out on a 7.3.

I also just found out the oil change place I go to didn't know I had a second fuel filter under my f350 6.0 2006. Hasn't been changed in 6 yrs. Will this cause my truck to have a hard time with having power first part of the day. Commons sense tell me yes . But you never know. Pisses me off that I bought the truck new and almost have it paid for and something simple like this could ruin all my hard work

well that doesn't help but I would also consider that you may have some injector stiction. I was having to let my truck idle for 5-10 minutes in the morning just to be able to drive it because it had no power. Just used rev-x for the first time and it seems to have helped quite a bit. I'm sure i'll still need injectors eventually but for now it'll be good, at least after I get the oil cooler and stuff done this weekend.

Uhhhhh yeah, that is definitely not a good thing.

Always a possibility.

I had a sticking no. 3 injector and had to plug the tuck in for awhile, even when it was warm out, just to get it o start decently. It would take a little while to warm up enough to drive. I used some rev-x a little over a month ago, and the truck starts great now. I have even had it sitting for a day or more in single digit temps, unplugged, and it will crank right up.


The best thing to do, in my opinion, is to replace both fuel filters, check your FICM voltage, and then go from there. It's too easy to test the FICM and at least eliminate it as the problem.
