Default No Start.......Any insight?

I have a 2017 C6 base model 6L
this morning it turns over when I push the start button , turns over good no start. Let off the start button and the starter keeps turning over the engine, push the stop button and it quits.
First thing I try is disconnect the battery for a while...No help. Check all fuses....no help . switch around relays of same part #. still no help.
There has not been any electrical work of any kind prior to this. I welcome any ideas that anyone may have.

I've seen that happen when the fuse box in engine bay goes bad. However without troubleshooting we will be guessing. Any codes?

With a crank no start you may have a fuel delivery issue…either a faulty low pressure fuel pump or no injector pulse…can also be ignition related…ie no spark…if you have a scan tool and can read RPM during cranking if you have no RPM that may signify a bad crank sensor…with a bad crank sensor you will have no injector pulse and spark…if you are not familiar with this testing seek out an auto diagnostic shop in your area…not a general repair shop or dealership…they will just replace parts.

Here are some diagnostic aids if you are attempting to diagnose this yourself…moving this to C7 Tech for discussion !!…OP, do you indeed have a 2017 ????

Don’t the engines crank around 250 rpm? Wouldn’t you see that on the tach if the cps was good?

On a C5 you will…on a C6 no (do a clear flood crank on your car and see if you see an RPM signal on your Tach)…C7 I’m pretty sure no also.

It's a 2017 and I found the problem...The Fuel pump fuse was making a bad connection, I tweaked the fuse legs, and it fit tight and problem solved.
Thank you folks for such a prompt response to my post.......now a Happy camper again.

If Corvettes are new to you the 2007 is a “C6”….a 2017 is a “C7”…what is a model “6L” ??

I’d say in this case a little more precision is needed:

Generation Years
C1 1953–1962
C2 1963–1967
C3 1968–1982
C4 1984–1996
C5 1997–2004
C6 2005–2013
C7 2014–2019
C8 2020–Present
