Hard Cold Start.....kinda

Hi all,

I'm having a wierd issue with my new to me 6.0. When the truck is cold (relatively of course since it's 90 out) it takes longer to start (It just seems to crank longer than a couple of friends of mine with 6.0's). After it warms up it cranks right over. When starting I always wait for the glowplug light to go out. I have installed a Scangauge II and have been monotoring the voltages and what not. I did find that my alternator was bad and just replaced it and trickle charged the batteries all day. Went to start it and the same thing.

I have monitored the FICM voltages and they are where they should be as well as the ICP, IPR, and HPOP.......Everything within spec. New alternator is putting out what it should also.

I'm at a loss here. I guess its not a real problem but it just doesn't seem right. The truck always starts.

Any ideas what else I can check??????


Thanks,
Steve

Does it crank slow? Or just takes a while for it to fire.

I'll chime in here on this one too. I recently purchased an 06 a couple of months ago and mine does the same thing you are referring too. I was searching on here to see what might cause this.

I have checked everything you have originally listed in the start. Mine starts great during the day, but that first start up after it has set for a while, typically overnight, it takes at least 4 - 5 seconds for it to start, but runs great after that.

I'm just curious is it something I need to be concerned with.

Thats what my concern is too. Just preparing in case something is getting ready to go South. Its almost like its not getting fuel at first. I've even tried cycling the key a few times. I also read to try it without waiting for the glowplug light to go out like a gasser. Still the same.

Ya i have been noticing the same thing on my truck. I bought my 06 a couple months ago, and it tends to crank over hard in the morning...longer than i think it should. I plan on putting a block heater in it for the winter, and possibly some aftermarket glow plugs to see if that helps to fix the problem?

me also

I am having pretty much the same problem. Mine seems to be getting worse every day. Anyone hear that high pressure oil seal could cause this?
