Okay purchased a 2016 corvette z51 automatic 3lt, bought it wrecked (main damage was just suspension and some cosmetics). Im having trouble getting it to start.
-New battery
-New 350 Amp fuse on fuse panel on top of battery
-New starter
It has lights inside and everything comes on but will not turn over only click.
Ive noticed sometimes when pushing start button the lights inside on rear view mirror will flash or dim out and the cluster will go out but check engline light will stay lit then it will all come back on. So that made me think there is a short somewhere and its been seeming like this i just dont know where all to check.

Also do these have like a crash or safety mode?
Ive done some searching my own but everything i tried didnt help

if it clicks, it's not a short.

Sounds like the starter or the solenoid. Have you tried to turn the engine over by hand? Pull several of the plugs to make it easy to spin. If you can't spin it....you have your answer. If it spins easy, that points back to the starter.

Also make sure the battery cables are tight on the battery. More than one person has had loose cables leading to a no-start.

on the newer corvette's can you try to manually turn the engine? (14-19) ? mines the 16

also would you spin it counter clockwise?

Pull plugs and spin it clockwise (looking at the front of the engine).

With the plugs out, you're not putting a ton of torque on the balancer bolt.

The other option....drop the starter and have it tested.

As mentioned before...make sure all the battery cables are tight. Many times people think the cables are tight but they're not. Try and wiggle them by hand.

Have (are) you checking battery voltage before and during cranking the motor? From what you have posted, you have not eliminated the battery; the fact that your lights are dimming when cranking engine points to low voltage . Just because you have put a new battery in, doesn't necessarily solve electrical issues. The car could have major parasitic draw going on while just sitting.....worth checking out; you only need a volt meter.

Good luck.

I agree, check your new battery's voltage to eliminate the obvious first.
New batteries have a high defect rate as they are compact yet very heavy and transported/shipped stacked on pallets and handled roughly with forklifts. You typically have more chance of having a bad battery at less then 30 days old than one that has been in trouble-free operation for 30 months.

Ok pulled plugs and tried to turn clockwise and would not budge. Im going to have another mechanic check it one last time tommorow.
The oil pan did have a small hole in it from accident or something hitting it so the oil did leak out. Also the housing bracket for oil cooler was broken but dented and still intact.

As of now its hard for me to believe the engine would be locked up still, but that is what seems like is going to come out of it. I still dont understand how unless after the accident the car was left running?? Also by how the suspension was damaged this car could not keep driving so thats my only guess is maybe the car was left running while the oil leaked out underneath


And how much the engines cost im unsure of what my plan is gonna be next along with needing all new knee assemblies

Somehow I don't think we are getting the whole story up front here.....so the motor has been locked up sense day one?

People comely leave the engine running after an accident, especially if at all significant. Their mind is elsewhere, a still running car is trivial.
