I have a 2005 maxima that will turn over but will not start.
I was driving vehicle an all of sudden it started running rough an didn't want to go an then died, hasnt started since.
After hacing it towed home i checked fuses. The essc/cont fuse was blowed, so i replaced it an everytime i would attempt to start vehicle it would blow. I found that the #1 ignition coil had shorted out (had a melted place on it), replaced that an fuse stopped blowing. Then I noticed that he alarm light stays solid red when ignition is on position even tho it isn't started. Someone told me it is in theft mode. How do I get it out of this mode? I have locked an unlocked car with key but that doesn't change anything. Someone told me to disconnect battery an turn lights on to drain all power from vehicle. I did that an when I plugged battery back up, the alarm started going off an lights flashing, sound stopped but lights kept flashing. Used key to unlock doors an lights quit flashing. Still will not start... im lost please help

 

Need an electrical wiz-kid, or go see your nearest stealership …

 

Your ECM is probably damaged. Scan the car. If you're unable to communicate with the ECM, the ECM relay in the IPDM is gone bad. Seems the bad ignition coil destroyed either or both the fuse (15A) and ECM relay which draws its power from the fuse. Both fuse and relay are in the IPDM.

 

Did you manage to solve the problem?

 

No

 

Ok, first thing i would recomend is to use a scantool, check codes, then add 2 ground points, one from battery to chassis and one from engine to chassis, after that disconnect one cam sensor and try to start, if there is no change then connect the one you previously disconnected and disconnect the other cam sensor, if there is no difference connect it and disconnet crank sensor, sometimes sensors goes bad, but not that bad to give you a code and mess the signals yo ecu.

 

Since my last post we have changed the IPDM, the cam sensors and cranksensor. Still will only turn over and no communication with obd2

 

Check the fuel injectors fuse under steering wheel and try to press it with your finger, I had that problem and when that fuse goes bad then there is no comunication with ecu, tcm, abs, and bcm, just comunicate with srs module, then add the ground cables, when I had that problem cluster CEL was off, when there isn't any comunication cluster will not turn on the CEL.

 

In the fuse panel inside the car?

 

Exactly, that fuel injectors fuse drives power to the ecu and other modules

 

Did the fuses an still the same. I'm not sure of I had mentioned it earlier but the fans run as soon as you turn car over

 

Then your ECU is dead, get an used one, and you could reprogram keys with Nissan Data Scan 2 and a kkl cable, as I do commonly

You most likely have a bad coil. same think happened to me, car just died and would not start for nothing.
Once a coil goes bad, it kills the starter fuse.

 

My brother just purchased an 05 Max about a month ago and we are fighting the same problem. Did you ever find the smoking gun? If so can you share. The only difference is the failure is intermittent. Failed and would not start for a week. Tested all fuses, grounds, ECU, relays, connections etc. Then it just started back up. Ran for about 6 miles and started acting up. Same code U1000. Disconnected battery, inspected all things again. Reconnected battery and it started. Have not tried driving this time yet. Thoughts?

 

Bad grounding maybe, or rusted ground wires, U1000 code is an error code related to can bus comunication, bad grounding makes that code appear too.

 

Agreed. Went through all grounds I could find yesterday and ensured good solid connections. Any specific grounds, sensors, wiring that are common failure points to focus on a 05 Maxima?

Could I have sensors, that are grounding internally intermittently?

 

Add a new ground from the top of the strut tower to the intake manifold, and try, I did it and worked.

 

Attached an extra ground as suggested. No such luck. After further driving and failing, it seems to fail when you hit a fairly decent bump. A few seconds later the vehicle goes into a limp mode: transmission won’t go above 2k, dash lights come on, no acceleration. All the fun stuff. This happened a couple times to me and I was able to just pull the battery negative for a few minutes and the system would reset the U1000 failure. The last time it happened today, I ended up having to disconnect the batter and the ECU. After reconnecting everything the car was able to start and made it back to the house. I also got a P1612 code the last time it dies out. 1st time for that code, assuming it is just a byproduct of the ECU not communicating.

Any further suggestions on something that could be loose or bouncing when going over bumps?

 

check the IPDM for loose connectors, limp mode could occur due to cam sensor failing, auto transmission need first cam sensor to work properly. Another problen I had with my max was a cam sensor failing but not showing any code and my car wouldn't start, so I disconnet one sensor at a time and try to start, that way I figured out wich sensor was fried.
