2016 Tahoe cranking start issue

[Mitzee]

Have a new 16 z71 Tahoe and it has trouble starting , like and old carberater . Been in to 2 dealers both say there is a problem but can't make it do it so gm won't let them try and fix it. Talked to lemon law attorneys and they say not yet a lemon

Any ideas ?

What kind of starting issue are you having. Is it hesitant to start

 

[Mitzee]

Starting issue

Yes, it cranks and I have to pump gas to get it to start, only happens 1 of 10 starts and dealer can't replicate but know something is wrong but does not know what to fix

Does it happen when the vehicle sits overnight when you crank it first thing in the morning?

Staring issue

Yes

I would leave it overnight at the dealership until the problem duplicates
