Crank time until start
I have a question regarding the crank time until start.
My truck has always taken 3.5 to 4 seconds to start either in the morning or after sitting for a few hours.
I always accepted that as normal.
New 6.0 starter last summer, two new batteries last fall
Recently had a bunch of work done, all new injectors, new oil cooler, new standpipes and dummy plugs, new IPR valve, cleaned turbo and ICP valve.
After all the repairs my truck takes the exact same 3.5 to 4 seconds to start.
I have read so many posts of trucks that fire in <2 seconds.
What would account for the "longer" crank time on my truck both originally and after all the repairs?
Thanks,
Art

Time that it takes for Cam/Crank or FICM sync maybe? You could chart all the PIDs required for starting in IDS/AE/ForScan and see if one is tied to when the engine actually starts, but IMO that's a lot of effort searching for a problem that might not really be an issue at all. Under five seconds is what keeps getting tossed around as "normal", so if your HPO PIDs read fine and it's otherwise all normal, just might be a quirk in your engine that makes it be that way.

Hi texastech_diesel,
I forgot to mention that a new cam/crank sensor was installed when all the work was done.
I'm jealous of the guys with the super fast starts! lol!
I don't think it is a problem I was just curious as to why some trucks fire in <2 seconds and other trucks, even with a bunch of new parts see no change in their "slower" starts.
Thanks!

Nothing wrong with those times Art. The farm I work at on the side has several 6.0's,one of them is a slower starter compared to the other two.

Yep, I did the 6.4 strter upgrade. You'd be amazed at the difference, starts much faster. $83 bucks from DB electrical, no core charge. (no, I don't work for them and they haven't given me anything for saying that, lol)
Getting the thing on/off is a real bear, imho, but worth it.

i have always had around 1 to 1 1/2 second starts. Ever since I purchased it I have religiously used Amsoil Diesel additive, along with fresh batteries and a new starter about a year ago

Mines always within 2 secs, use synthetic oil and premium grade fuel. Always wait 4-5 secs after the light goes out before cranking as that seems to make a difference - quicker to fire up and cleaner idle straight after

It can be standpipes drain down, or LPOP is a little slow I think poppit in filter can do it. Also a ICP thing the list is pretty long.
A bit of salt while I'm here too 1-1.5 seconds and mines lit off.. Also 6.4 starter along with a big cable upgrade pushing lots of energy around.
But a 3-4 second grind is not anything to worry about.
