05 pathfinder finally fixed

[selliott]

Yes we checked both vtc solenoids, oil pressure etc, I'm pretty sure the timing isnt off its reading equally advanced across both banks and it varies so I'm thinking it's just the ignition timing and it doesn't run long enough to straighten out and if we pull the inspection covers and rotate it over by hand everything lines up. I have now changed the ecu (plus paid nissan for the reflash), and the ipdm. I have no idea what's wrong, this weekend we will pull the trans to inspect the flexplate to make sure it's not damaged and giving a weird signal.

Finally found the source of my headaches

Well, that's a first I've seen on an R51!

[selliott]

Neat huh lol

[Thupertrooper]

Theres your problem lol

[selliott]

Wish I found it $3000 ago lol

[Kestral]

Ok so help out a guy who has never seen one of these? Is this the trans flex plate we are looking at? And I assume all the missing pieces and what looks like broken areas is not a good thing? And why would this cause the motor not to run?

By the way the inside of your motor looks real clean.

[Kestral]

Another ? Where does this plate mount to? I assume between the motor and transmission?

[Thupertrooper]

Could be a nut fell and jammed up the plate. Do you have pictures of the rest of it or teeth?

Yes it is the flexplate and no it's not a good thing lol. As the flexplate spins the crank position sensor reads the positioning but since the center was broken and had allowed the outside portion to move slightly it made the timing off and the ecu didnt like it and shut it down after a few seconds of running. If that makes sense I didn't do a very good job with the explanation.

The teeth are all still in great shape for 230k anyways. I'll get a better pic tomorrow

Only other thing i can think of it high rpm transmission sudden change that is strange.
I would think you would hear more noise out the back with that kind of damage.
Good thing you figured it out finally it was about time.

Yeah I'm not sure what caused it, I did hear a tick coming from the bell housing when this first started but it didnt sound like a typical broken flexplate tick so I took it to a shop and I was told "don't worry about it" lol. Yes Im glad to have it back, it sat for 2 years until I had the funds to tackle the timing components, radiator, and possible trans rebuild.......turns out I just needed to replace the radiator and flexplate, oh well all tsb issues have been addressed. Now I need to do some research on tuners I was looking into the bully dog systems.

WOW!
incredible perseverance on a really tough diagnosis
selliot, my hat's off to you
