So I have an 04 Maxima se. Whenever I bought it I did in fact buy it knowing that it had a hard start/no start condition. I did some research and found out easily changing the cam/crank sensor generally 95% of the time will in fact fix this issue . The car was in great shape and had about 145,000 miles so 500.00 bucks was a steal.. Now let's fast fwd 4 years 1 new timing chain kit replaced countless cam and crank sensors 3 new from my local scrap yard complete engine wiring harnesses and 8 (yes I said 8) ecms. 5 new bcms and 4 yrs of migraines, countless long nights 3 OBD II scanners 1 girlfriend and possibly a sec one later and I'm still no further with this POS than I was the day I went waddling and Quaking up the lil fellas driveway to purchase the car.. I do know the car will in fact start and drive if I was to unplug the Bank 1 cam sensor but it immediately sends the car into failsafe mode and the transmission is stuck in 5th gear. Even if I was to start it and then plug the sensor back still in failsafe. The new scanner I have does give me live feeds and I have noticed that the timing on the Bank 1 and Bank 2 intake cam timing are drastically different. As I've stated before I'm evidently not as smart as I thought I was but shouldn't these 2 cams be running somewhere close to the same timing.. Bank 2 and an idle is somewhere around 0 to -2.5 degrees. Whereas Bank 1 is always a steady 65 degrees. As I stated I'm not a smart man but imma gonna reckon these should be close. And of course I have the P0340 continuously and every now and then I'll get a P1212 and a U1001 codes. Somebody please help or send dynamite cause I'm fixing to send this car somewhere. Be it down the street or pack the trunk with enough dynamite to send it right back to Japan in one loud bank. At this point it really doesn't matter to me either way.

 

Seems as though you have several seperate things going on here..

Have you checked the solenoid it self..?
Everything you have replaced has a Test.. Download the FSM and Get to it.

Was the timing done prior or did you have that done.?
Does this car start In 5th gear, always or just after moving the car any distance.?

 

All the work that I've stated has been done by myself. No one has turned a wrench on this car but me. Since I've owned the car..
The car will drive but only in 5th and another unknown gear if you downshift.. but the only way the car will start is if I unplug Bank 1 cam sensor..
I have tested and tested I just don't understand what I. An be doing wrong and it's gonna be something so simple I'm gonna look like a retarded poodle puppy whenever I find out what's a wrong with it

 

Myself and several other people that have looked at it don't quite understand how it's starting with the sensor unplugged but it does... And just to clarify the car was in this condition prior to the timing chain breaking in half.. I was kinda happy whenever it broke cause I thought it would fix the car but I was wrong same gremlin upon completion of the repair...

 

I have replaced the IVT Solenoids this past weekend no change
