2010 silverado starting issue

[wvetre]

I have a 2010 silverado with a 5.3. It has 29000 miles on it. when it first started getting colder in october i noticed when i cold started it it would crank then studder or hesitate for a second then start and run normal. Now that its in the 30's it sometimes it will studder or hesitate for 3 to 4 seconds before running normal. Has anyone experienced this or had this issue before.

Not normal. Hopefully, it will throw a code, so you don't have to guess at it or try to get the dealer to "duplicate the issue". If it always does it when cold, then I'd let the dealer sort it out under warranty.

Mine does this on rare occasion. I've never been able to sort out what conditions is reoccurs with so I haven't bothered. It's so infrequent the chances of it happening for the tech are about the same as winning powerball.

One thing to consider: turn key to "on" for a couple seconds before starting. That should energize the fuel pump and build pressure before keying the start sequence.

Ok thanks i will let you know what happens. Of course today it was about 20 out and it only studdered for a second.
