Long Crank on the 6.7
 

Does anybody have the long crank issues on their 6.7 like we had on the 5.9 standard trans

Here so far so good

Mines not bad but seems like it should start upalittle faster takes 5 or more seconds

Mine is almost immediate. Certainly not more than two seconds.

Forget to say mine does it 50% of the time the rest it starts right up

Same here.

I find that if I wait a two or three seconds my truck starts right up. If not it will take much longer than my 5.9.

i was just about to post about this problem.. my long crank is intermittent also. sometimes it will start right up within a second sometimes takes about 4 seconds it only takes long like 30-40 percent of the time though..does anyone think this is a problem?
Dont ask why but i ran out of gas before with but put a gallon in bumped the starter and it started right away. read that there is no prime button like the old 5.9s

I have found that If I just jump in my truck and try to start right up sometimes I get a longer crank time. If I let the chime ring once I find it cuts down on the crank time.


But relatively, its still a rather long crank time compared to my '90. That sucker fires off on a half spin of the starter.

I am having the same problem sometimes it starts right up and other times it takes a few seconds hope it is not going to be a big problem. I did notice the other day after a road trip of 400 miles and the batteries fully charge it started right up everytime so i am wondering if it might be the batteries going bad

Ive already had to replace the batteries on mine. Passenger side was bad. It wasnt a long crank issue though. It was a no crank issue.

If you treat it like a computer and let it boot before you start, it seems to keep it from having to catch up on the go. Even without the grid heaters, I let it sit for 5 seconds before cranking. The 97 is "dumb" and only needs a spin to get the fuel going, no computer there to fool with..

Makes perfect sense

True, that's the secret.

I was just thinking. That may also have something to do with the long tip start cycle on the new '10's that pop up every once in a while.

I always wait for the five "dings" before I bump the key or switch. Seems to be fine.
