Engine will not start, seeking ideas

DIGItonium

Reverse battery connections... wow. Sorry man... you'll probably want to see if you can have Nissan pull stuff up through Consult. If there's no response from the ECU, she's dead, Jim.

As for engine dying and sputtering from hard turn with 1/4 tank, yea that's fuel starvation. IIRC, the work around is to manually fill it up to get it started again.

That's my main worry, fried electronics. I only ask because I don't know but if every other electronic device works (windows, locks, wipers etc.) is that a good sign? It just won't turn over.

As far as i know all the interior electronics are seperate from the ecu so even if they turn on it doesnt neccesarilly mean that the ecu wasnt fried by the idiot driving the tow truck...not even sure how he got the connection backwards since theres a huge freaking red cap over the positive terminal

DIGItonium

My coworkers and I overheard a guy on the other side of the wall talking about how he switched polarity on the battery connectors. He literally thought black meant (+), and he said something along the lines that he has been working on cars all his life. Mind = blown.

[sigh] I guess you'll just have to walk out with a 2015+ NISMO.

This happeneds alll the time with battery terminals, am sure nissan has prevented anything serious happening to the ECU, but some other devises might be damaged, letting the voltage come from ground where alll of your electronic devices are connected to, means if on the other end the switch is in on position might damage the hardware, also the ECU might lock out to prevent damages until it is reset. Just a thought.

Now am thinking steering wheel locking mech?

It's a 2012 so I wouldn't think lock. Thought that was rectified in or around 09-10. But hey I hope you are right and they can just reset it

Most of the non-drivetrain stuff is controlled by the BCM. ECM and TCM handle the drivetrain. Ie, ECM could be fried but windows would still work.

Starter fried, they can get it started via push, drop clutch. So, not to bad, not good, but not as bad as it could be.

I would be asking the tow company for reimbursement at this point...good thing the ecu wasnt fried, but still not a cheap fix having to replace a starter

Jordo!

Yeah -- wow.

But if it spluttered out coming out of a hard right turn, you probably had fuel starve too.

The failure to turn over issue was just an unrelated problem. I'd check your battery and alternator too as well as inspect fuses.

Connecting the cables on the battery backwards.. not good :/ My friend lent his GTR to someone who did connected the jumper cables on backwards and fried a bunch of electronic modules that had to be replaced before the car started again. May be something similar in this case? Although for my buddies case his friend actually left the cables on sparking for an extended period of time, like 10 or 15 minutes >_>
