Hey guys I have e a 2006 350z and I was driving one night when car suddenly turned off checks battery and cable was loose so I righted it car started no problem drove to Walmart a couple min away turned off car now it went start I've read a few things on here and still won't start I've changed camshaft and crankshaft sensors and immobilizer reprogrammed and gotten new keys led light stays on and car will only crank also replaced fuel pump and this point I'm honestly considering parting out car any ideas would be greatly appreciated

 

Sounds like nats

 

Is it worth it car has over 216k but rebuilt engine

 

Only you can decide if it's worth it. A Z can last well over 216K if cared for properly. Take all your ownership info to a Nissan dealership and see if they can use CONSULT III to reprogram NATS.

 

Any idea what that may run me lol all the parts I've bought are OEM so Nissan already taking my money lol

 

Most dealerships charge an hour of labor to do an initial diagnostic. You might call around to a few dealerships in YOUR area and consult with their service departments to get an idea.

 

Can you hear the fuel pump kick on when key in ACC position? My guess ...poor battery connection caused a failure to your fuel pump relay.

 

If you have a NATS issue - I gotta guy. DM me.

 

Fuel pump seems like a good guess if it has 200+k miles on an original pump. A loose ground wire shouldn't shut off the car if it was already running. The pump is noisy so if you push up your pass seat remove the junk from your glove box and pull the little tray you will defd be able to hear if it's turning on or not.

If it is key reprogramming issue a good locksmith can reprogram the keys. If you have roadside assistance from AAA or another place like that they might offer locksmith services for free or at a discount.
