Attempted to start, engine turnover strong (battery good), sounds like no chance of ignition or firing. Had car towed to Chevy dealer, replaced ECM and fuse block, no change, no diagnosis codes, any ideas or similar events? Please share, thanks in advance

Fuel pump maybe - I know to obvious - good luck

Can hear fuel pump prime when I hit start button. I suppose it could be downstream from the pump but pulled out of garage to wash after a 100 mile trip and started fine, backed it in and its been shut down for a week. Then the no start began and hasn't run since. Flatbed to Chevy, changed ECM and fuse box thinking it was electrical. Just sitting at Chevy as they go through diagnostics to with no codes or success

The car is at the Chevy dealer, right? Isn't the onus upon them to figure it out? Did they ask you to do the diagnosis? I mean, are they that incompetent?

Thank you! I hear ya! With no codes its just so frustrating to have the service manager say after a week of being in the shop, well, we "think" its electrical but don't know at this point. Maybe I should be asking the forum, what can be said or done to pressure Chevy to make this a priority rather them ordering parts? waiting a few days, install and failure. I was just hoping there was a record of a similar repair for Chevy to reference.

Just saying, that if I were a tech with a not start condition, I would check fuel pressure & spark before I would be changing out parts, check the 3 basics, fuel, spark & air, none of those would likely set a code, then start digging for the electrical & mechanical issues.

I would request that the dealer technicians engage directly with the Corvette technicians at GM. I am sure if they speak to the right engineers at GM they will offer a better troubleshooting approach then just throwing parts at it. There are a number of systems involved when starting the car. They should be able to log what is happening and share the results with the GM techs so they can provide better guidance.

Fuel, spark, air... that's all there is. Btw, it's GM's job to make it start... EVERY time. All the best!

Thanks for the insight! Will be having a conversation with Chevy on Monday.

Thank you and appreciate your answer today!

I don't have any good advise as the three basics would be all I could say. But, I wanted to say good luck, and I hope they find the problem soon. I can understand how sickening it is to see your brand spanking new C7 just sitting at the dealer.

Air, fuel, spark, at the right time!

I had this problem with C6 - they called GM could not figure it out themselves finally it was electrical problem ripped interior apart to find issue - I traded it back in could never trust it
