Normal start time for a 6.0? When to change glow plugs?
 

Seems like when I used to turn the key it would start within 1 second (or less after warmup). Pretty much like a regular gasser...

Lately it seems like about 1 1/2 to 2 seconds

What is normal for you guys?

I have 105,000 miles and always use a the Amsoil diesel fuel conditioner

Runs like a top but this later start thingie bugs me...

Thanks for the replies

Pretty normal cranking times. Might check and load test your batteries and see if they check out ok.

I've never timed it....but 2 seconds would be my SWAG.

(scientific wild ass guess)

Mine is a one potato two potato girl, sometime 3 potato when she is ornery and when the temps are below 20* she might take 4 potato's!!:-drink

I would be happy with a bump-n-run start.
But am happy with a grr-n-grr start. Under 2 sec
start most times.

Sean :-drink :-fire

Mine starts fairly quickly cold and hot, it's the 5-8 hour inactivity that gives the inconsistent starts, but still under 2 seconds.

Same here. Sometimes it fires like a gasser. Sometimes takes about 3-4 secs.

New batteries, different gas stations, outside air temperatures. Makes no difference.

I even tried to park truck up hill and down hill just for S&G's.

As long as it starts. I'm good. When it really dies. I wont miss it.

My crank time is inconsistent. Sometimes it seems to fire as soon as it cranks, other times a few seconds. Started it today after sitting more than 24hrs and glanced at ScanGauge, EOT and ECT were at 92°! Pretty warm here lately.

The glow plug system is pretty good at correctly throwing codes if there's an issue. I wouldn't worry about them until you get a Check Engine Light.

I have this same situation. Mine started with a touch of the key for a long time and now it is very inconsistent:-X15 I would love to have those quick consistent starts back but as long as it doesn't get out of hand I guess it is ok

It seem like after the Injector buz and the HFCM quits 2 seconds and BAM we have Diesel start:-jammin X2 on the Battery's check may as well check the Alternator too that's the big Killer:-X22

Even with that crackling noise?? Lol

With everyone that calls there truck SHE do you really need to ask about inconsistent times?
Just be happy and it not like my sister. She used to say be ready in 10 minutes... Right Sure
45 minutes later and we are still waiting.

LOL yes may be even less cranking time hahaha:-X04

I too "was" frustrated with this just like a month ago, my Truck for the last 3 years has Always started immediately & all of the sudden it started taking like 2 seconds to start :confused:
I had actually taken a short Video & was going to post on here, but there's a new local shop I stumbled upon (powerstroke gearheads) & I stopped to talk to him & he told me that I have absolutely NO worries, a 2-3 second crank time is very normal. In fact he seemed stunned @ how fast it was starting & that was a long start to me. So I quit worrying about it........

Here's the Video I shot, cranking starts @ 9 second mark & appx 1.5 seconds long :-wink

Lol! Very true, I swear my truck has a personality. Sometimes it's ready to go immediately in the morning-sometimes it's got to get up 150° ECT before it pulls and shifts right. I've paid attention to where I bought fuel last, outside temps, oil changes, how quickly it starts, and lunar cycles. There's just no pattern to it I can see. :-X21 when I turn the key I never know what I'm gonna get for first couple of miles. It always runs great after it gets a little heat in it though. I'm blaming mine on injectors/stiction...for now.
