My Titan will intermittntly crank without starting. Eventually (between 30 seconds and 10 minutes) it will start up. Anyone else have this problem? If so, what is it? The dealer says they have no idea what would cause it and they can't fix it without creating the failure.

How many miles do you have on the truck ? Where are you located ?

ohhhhhh, and there's an e in intermittently :) :computern


FYI Higher millage vehicle's are prone to carbon buildup that can cause this issue .... easy fix....

10K I doubt it's carbon, I would check the MAS sensor, fuel flow (pressure), on a far out there theory it does sound like there may be air getting into your system somewhere, check all the vacuum hoses around the manifold and check for fuel leaks after you have the trouble starting it, hows your millage (you wouldn't see a huge drop with a small leak); Are you parked on a hill when it's does this ?

Have you ever checked/ changed your air filter ? Give it a peak if it was REALLY dirty it would give you issues but pretty regularly though...

Let me know how it works it for you....

It's "that" time of year with people posting up "unknown" problems as their first post. Have to keep that in mind...

And an '07 with 10k miles that has an intermittent starting problem is a warranty problem. If it does this frequently then leave it at the dealer and let them deal with it. There's no reason the owner of a new truck should have to spend valuable time checking fuel pressure, MAF, vacuum lines, etc. That's ridiculous.

More ridiculous are the rash of "My Titan has a problem" first-posts that often times are nothing more than trolls trying to stir up crap on the boards of a competing vehicle. My apologies if that is not the case here.

If this is a genuine problem, then my guess would be a faulty immobilizer key or control unit. There is a chip in the key (The keys with the silver Nissan logo are the ones, the ones without the silver logo don't have the chip) that sends a signal to the control module telling it to start. If this is faulty then the engine will crank but not start. Your truck should have come with 2 such keys and a 3rd non-chip spare key. Try using the other chipped key and see if the problem goes away.

Sorry the problem is unknown and my first post. I have owned nothing but Nissans since 1998. This is my third Nissan truck and I love them. This is definitely a real problem.

I tried taking it to the dealer and they weren't very cooperative. It's only done it maybe 6 times in the last two weeks. Kind of hard to go several days without the second vehicle.

This is my wife's vehicle. I am now driving it with my key instead of hers. We'll see if that cures the problem. Sorry to see you are so skeptical. Please remember not everyone who posts for the first time is an idiot. I know the difference between the "chipped" keys and the valet key.

I never claimed anyone was an idiot, some people are just ignorant to the fact the there's more to the pretty keys than being pretty. I wanted to make sure you knew as most people probably wouldn't. :cheers:

Hang around here long enough and you will see what I mean about troublesome first-posters. The skepticism is there for a reason. ;)

Good luck and let us know how things work out.

First post or not I will still try and help a "true" Titan brother....

And I'm of the "I'll fix it myself" school and only bring it to the dealer when I don't have the tools or knowledge, that way I know it's done right....

I've had terrible experience with dealers (not Nissan though)

Mazda dealer dropped my new Mazda6 off the lift, it had less than 3000 miles on it, took them weeks to fix it.

Same Mazda dealer replaced my clutch and forgot to put a lock nut on the top swing arm (leaving the dealership the wheel and hub assembly popped out broke the break line damaged the wing, bent the strut top damaged n/s door the list goes on and on... )

I've had Subaru charge me for an Airfilter and not put one in. $28

OK I'm stopping my rant before this turns out to be 3 pages long :jester:

Just to clarify guys, the Valet key also has a chip in it!!! The only difference between the master keys and the valet key other than the lack of a silver Nissan logo, is the grooves on the key are slightly different, so that they won't enter certain lock cylinders. But Master, or Valet key, they ALL have the chip inside, unless you have an XE King cab...

When the Chairman of the Board of Nissan says he is thinking of dropping the Titan from their lineup due to poor sales, TT trolls become a very small part of the problem.
