2006 M35 Dead, wont start or do anything HELP PLEASE!

[1slickm35]

Ok , so hear are the details.....just randomly I leave a friends house crank the M and I get Service engine soon light , SLip and VDC OFF light , I wasn't to worried as ive had this issue before and I replaced the Crank sensor near the oil pan and it fixed it. SO I cut the car off and restarted just to see , it kinda hard started but started and I drove it home , no issues driving home. So when I get home , I decide to disconnect the negative battery cable just to see if that will reset the codes and maybe they go away.....so here is the crazy part to me. I disconnect the battery cable and leave it for about 30 minutes and then connect it back and now the car wont do anything ?? Not anything ...no noises of a starter , wont try to crank ....just dead. I press the button and nothing happens at all. Ive tried putting the key fob in the side port and still nothing.

However , I do have power for headlights to come on , brake lights and interior lights come on. No lights on dash , even the push button start is not lit. Also the security red light on dash is blinking. Another strange thing is my key fob doesn't do anything now either??

Things i've tried so far , I cleaned the negative cable and reseat it several times , checked the battery with multi meter ( checked good) and i've even tried to jump it off and still nothing. Checked fuses and found no problems there.

I have no idea what I could have done ? Any ideas ? or it looks like i'm gonna have to get it towed to the shop I use and hope they can fix it.

Thanks for any help you can provide , ive done a lot of searching already on here and haven't found anything like my issue.

Welcome to the forum.

How many miles on the car? It kinda sounds like your alternator went...but the battery still having charge is weird because usually when an alternator goes the battery doesn't get charged and thus goes with it (until a new alt is installed). This results in NOTHING happening, no lights, no starter, etc. I only say this because all your fuses and relays checked out...the next thing that's really left is the alternator.

Thanks for the reply , the car has abut 150K miles on it, however even if the alternator was bad I still think when I tried to jump it off that would have fired it up but it still didn't do anything ?? Plus whats the deal with the key fobs also not working all of a sudden ? I know these cars have a lot of electronics in them so I really think its no telling what could have went out....just wondered if anyone else had experience anything like this. thanks again for your reply

Well the car gave a warning sign and you ignored it. Get it scanned...Hoping the code has not been deleted.

[1slickm35]

I'm not sure how I ignored it?? I tried to fix it by resetting things by unplugging the battery (which is a common practice to reset things on cars) to see if that would help. Also I had the dash lights like that before like I stated and knew what the possible problem was. BUT thanks for your Help ??

Isn't the point of the alternator to keep a car running once it's started? At least that's what I thought...honestly I'd still get it checked out...

As for the key fob and some lights working...I'm not sure. Without seeing the car or knowing what the code was in the ECM...it's hard to say. I'm just trying to get the car started or get you on the track to getting it started...some of the issues you are encountering may be secondary.

[1slickm35]

Yes , that's correct, Once I get it started. However it wont start. Alternator comes in after its started, to keep the battery from discharging. The battery checks good and when I tried to jump it off I still got nothing. Im starting to think its some kind of security feature because of the blinking security light and that's why its shut down. I know there is a Immobilzer feature but I don't know if that can be reset ? Never had a car just do nothing but have power to headlights and other stuff but not crank a lick ..very weird.

Is there any aftermarket remote start on this thing? We just had another member go through that...car did nothing when he hit the start button. See this thread: help-m35x-stranded-me-how-to-bypass-bra ... 10429.html

As for the immobilizer...my knowledge with that is from my old 99 Maxima SE, but when that went out I simply towed it to Nissan (they need the car to connect to the ECU) and they reprogrammed my key again...cost like $80 total (I had AAA at the time so towing was free). What my Maxima did was basically not allow the ECU to send fuel to get it started. Car would start if I sprayed starter fluid, but not otherwise. After the programming, car was fine till I sold it.

Precisely. By "resetting things" (i.e., deleting the code) without knowing what you were erasing was ignoring the warning. The fact that you did it before does not mean you solved the problem. The crankshaft sensor you swapped out earlier has two other blood buddies,namely, camshaft sensors. With the high mileage you have, the camshaft sensor(s) may just be the cause of your issue. Get the car scanned.

It's the battery. Batteries can still power the lights and such when they have gone bad. They just can't handle the load of the starter. It is pretty easy to check with a booster or take the battery out and take it to Autozone to get checked.

I pretty much have no choice but to get it scanned and/or looked at by a shop. However , not sure if you know that the purpose of a forum is to help people try to fix their cars, give suggestion on possible things that could be the problem....not be a smartass jerk know it all that really isn't providing any help to the situation ....what are you bringing to the table that I already didn't know without posting for help in this forum and trying to avoid a trip to the shop???

I know I know .....take it to a shop and get it scanned....awesome advice !!! WHY DIDNT I THINK OF THAT ???



Thanks again King of SCANNING !!

I may get it check at autozone just for the slim chance it has a bad cell I guess , but I did check it with a multi meter and it showed enough volts to crank, I also hooked it up and tried jumping it with a battery starter and jumping it off from another car....still got nothing ..so I kinda felt like it was something else. Thanks for your suggestion though ill give that a try just incase.

Frankly, I'm oblivious of this insinuation. I quite agree with you regarding the purpose of a forum. But then there could be a motley of confusing and misleading suggestions if as you did you destroyed the principal evidence by which assistance would have more rewarding. Glad that you have chosen to retrieve that evidence.
Cheers.

Agree with Sstupid, I had some really strange things going on with my '06 M45 and my battery's voltage looked ok with my multimeter, but it failed miserably under load - got it replaced and problems disappeared. There have been several posts by others on strange electrical gremlins in their system and for quite a few, it ultimately was a bad battery.

good luck with finding out the cause, and let us know how it goes.

Now now fellas, lets simmer down.

[whitewolfdog74]

I know this is and old topic but I'm having the same problem.Did 1slickm35 get it figured out?

[Rexa7993]

1slickm35, did you ever find out what happened with your m35? I have the same exact symptoms!
