Different frunk issue
Leaving our monthly Vette club meeting one of our members comes and gets me saying he has a technical issue. Went out to the car and it turns over but no start. All doors hatch and frunk closed. Car was getting fuel but appeared to have no spark. Owner calls OnStar for a tow. While he's on the line with OnStar his wife was telling another member they had the frunk open before the meeting to get a cooler out. I waited for the owner to disconnect from OnStar and walked to the front of the car. The frunk lid was indeed closed but on a whim I pressed down on it and the car fired right up. I'm guessing an adjustment or a switch is not engaging properly. It goes to the dealer tomorrow.
On another subject, will the car start with the hatch or either of the passenger doors open? I'm not a C8 owner yet but was told by another that everything had to be closed before it would start. Sounds odd to me as other gens will start with hood or doors open.

The problem is the frunk was completely closed. I had to push it down further to engage whatever switch enables/disables the start function. This car definitely has a problem and needs to be fixed.
Still need an answer to the question can you start the car with either passenger door open or the hatch open? I have already seen it doesn't start if it thinks the frunk is open. Thanks.

No indication. The lid was fully latched. By me pressing it down farther is what enabled it to start. Haven't heard if he took it in to be fixed yet. I'll follow up when I find out.
Funny side note: When I pushed down on the frunk lid and it fired up I felt like the little boy in the VW commercial that was using the force on everything when his dad used the remote start to make him think he did it.
Since I do not own or have access to a C8 my question still stands: Will it start with either passenger compartment door open or the rear hatch open? Thanks.
I know it will start with the driver door open. I started mine yesterday with the door open (not remote start).
what about Frunk?
If what OP observed was accurate maybe a simple misaligned sensor or too "touchy" hoping for the former not the latter or this will be the next thing talked about until my eyes and ears hurt.

As soon as I hear what the fix was I'll post it in this thread.
My guess is it was just a coincidence. I don't think there is a separate sensor that would allow the car to crank over but not start. It would either not allow the car to crank over or allow the car to start. Allowing the car to crank over but not start as a safety feature doesn't make sense.
There have been other gremlin reports of the car cranking but not starting but then starting after trying again.

That's what I thought originally. We tried multiple times to get it running and all we got was the starter engagement. Once I pressed down on the frunk lid it fired right up. I'm just as baffled.
And, the frunk press could have been no more than happenstance, having nothing to do with starting... but with these things, at this point, who knows? I'd be surprised if the dealer finds anything amiss.

like when I hide the key fob from the kids and they say hello to the car and the lights come on?? Hahahaha . Could be.
I do remember a funky fuel cutoff switch that if you banged on the quarter panel of my old Ford would get it to start. Left it like that for a while. I pretended I was Fonzie for the crew.

I don't think any car's had a fuel cutoff that allows the starter to run/turn over (agree with RKCRLR). I agree (avanti) that, unless it's been written by someone at GM, the dealer's not going to find it/the problem at the frunk because it's not there.

I'm in agreement with you. I don't think it is a fuel cutoff issue as you could smell fuel at the exhaust while it was cranking. I think there is something in the ignition system/computers intermittent. Like I said it would turn over, it just wouldn't start. It would also turn over with the rear hatch open. I'm sure the pressing down on the frunk was coincidental but it was odd that it fired right up after I did that. Still haven't heard back from the owner yet. The dealer is going to have fun with this one.

Ford just about every coupe and sedan back on the early 90s did. And it was a magic act for someone like the OP or me to walk over perform a little fonzie-esque pop and have the engine light up. The car used to crank over and over see video. I see they haven't changed lol
technically its an inertia switch. Meant to stop fuel from pumping in an accident BUT every now and then a big pothole or bump or anything would "pop" the breaker so to speak..

Hmm, 17 posts and no answer! Just went out, popped the Frunk and started the car; cranked and started as usual. Pic on Dash of car with Frunk open and words it was open!
I am corrected, 19/C7Z. If Ford than maybe others. But doubtful this gen or prior gen Corvette.
And I've actually read about fuel cutoff switches in cars in case of accident (didn't know they were so sensitive that a big bump could activate them). But I thought they were computer shut-off, not mechanical switches that determine or are told to switch off. Here, I'm thinking of computer command directly to electric fuel pump to stop. But that's Ford. Of course, there "could be" a new invention by GM, and maybe for more than just the C8. We will see. Thanks.

FIATs made in the '70s had electric fuel pumps. There wasn't a requirement in Europe to have a fuel cut-off switch but there was a requirement in the US. So the import versions added a fuel cut-off switch. It could be seen in the schematic along with a fuse but they didn't discuss the system or locations in the manual. Instead of being integrated into the harness they put a single wire in with an inline fuse underneath the back seat carpet.
It took me a while to figure out why the engine wasn't getting fuel when the fuse blew. As I remember, the switch was bypassed when the starter motor was cranking. So the car would start but wouldn't continue to run.
