Cold Cranking Procedure For V36

Hey guys,

Just doing my homework here but having my V36 sitting in the garage for the past 5 months and never started, I need to figure out the cold cranking procedure for these vehicles. It's a ritual I used to do with my old Maxima whenever I got back home from such a long absence, changing the oil and filter as well as taking out the spark plugs and dripping some oil down the cylinders and then finally cold cranking the engine without fuel for about 30 seconds, or until sufficient oil pressure would build up.

Of course, back in the day with an old '92 model car, that was a piece of cake with the old ignition barrel but now it's a push-to-start system so it's trickier.

Is there an elegant way to do this or will the ECU freak out and avoid powering the starter motor if I were to remove the fuse for the fuel pump? Otherwise, my other option will be to manually actuate the starter motor using external wiring at the IPDM in the engine bay instead.

There is an "elegant" solution, in either getting diagnostic software (uprev) or buying Consult (14,000) and using that to turn off the fuel pump and release fuel pressure when the car is cranked. However, as the others have suggested; just start the car mate. Its not a EH Holden...

Plus cranking it will kill your starter prematurely.

Excellent. I have both the Osiris Tuner as well as a Nissan Consult 3+ kit ($1600 Chinese knock-off with software). I'll do my homework when I fly back home soon.

As for killing the starter motor, it's easier to replace one of those than it is to freshen up an engine. I can live with that. My Maxima lasted for 16 years before the starter needed replacing and that was after a course of 4 cold crankings over 8 years.

The VG was better for it.

when you turn on the ignition (to connect to the ECU), the pump will prime and pressurise the system. Using Cipher, turn the fuel pump off. Car will start briefly, but run out of fuel and die quickly. Then I guess you can crank if you want. I guess other options would be to disconnect your fuel pump via either the fuel lines, or the electric power to the pump. Might throw a CEL then.

But I'm still of the just Start the car camp... :)

Agree with the others.. Don't think cold cranking is necessary. Never did this in my old maxima after extended periods of inactivity. Never had any issues with it. It didn't burn any oil and ran great until a broken crank snout shot it dead at 290,000km.

Not a fan of cold crankIng. As long as the fluids are in relatively food condition, I wouldnt bother. Just be gentle until everything starts flowing like it should. Then you can really give it to her.

Does that sound sexual? :/

Heheh. Not really that sexual considering my car is a bloke for if it were a female, I'd be more of a gentleman with it. :P

Anyway, thanks for all the tips guys. I'm not going to start a debate about the pros and cons of cold cranking, as that wasn't the aim of this thread, but at least now I know what I can do to perform it. I'll have to get my hands on the manuals for the Consult 3+ software to gain a little more insight before I get back home.

Thanks again guys.

      There's probably an underlying issue with the A/C system too. I recently fixed mine, now it's fully control by the Haltech and car's factory HVAC controller  Have a squiz here:

      And by the way, I've also checked the ECU diagnostic numerous times and got a bad O2 sensor code and initially an Ignition Primary code, which is why I replaced the O2 sensor and all the ignition components (coil packa, plug and loom). No codes have been coming up lately despite the ongoing issue.

      Hey pber13, unfortunately still no luck. At this point the following has been done with little or no success: - Spark plugs replaced, gapped to 0.8mm - Splitfire coilpacks installed to replace originals - Replaced Ignition Coil/Coilpack harness with a new genuine nissan one - New fuel filter - Replaced AFM/MAF sensor - Injectors have been thoroughly cleaned with an online flush (without removing) - Upper engine and inlet decarbed - blew tons of black smoke out, cleared the carbon deposits from the top of the engine and exhaust.  - IACV removed and thoroughly cleaned with carburettor cleaner - O2 sensor replaced with new and genuine one -  Smoke test revealed no vacuum leaks - Healthy compression test of 160psi across all 6 cylinders Overall the car does run a lot smoother now, no backfires between gear shifts like it did originally... but the rough idle when warmed up is still there. It may not even be a misfire but simply a rough idle. Seems crazy to me that so many people have had this issue and seemingly no one has gotten to the bottom of it, or at least never bothered to post if they did! Hope you have more luck than I did pber13, I'm at a point now where I'm just going to try to ignore it unless it gets worse. Would love to fix it but I've genuinely run out of ideas of what it could be.

      I got the full frenchys kit too. Really awesome kit. Easy to install my only complaint was the hardlines I think could be routed differently (I modified mine) but I realise the kit needs to suit multiple applications. This was the hard lines before I modified them. They were touching the wastegate pipe. I ended up reducing the distance between firewall and first bend. The made it so they tucked along the frame rail.

      Deeve, I don't suppose that you've made any progress on this? My Stagea has the exact same problem, and just like you, I've read through as much as I can online, with no real progress. My car isn't throwing any codes at all, which is a little frustrating. I've changed plugs, checked the wiring and harness. A new MAF gets here next week, but I'm not hopeful it will solve the issue.
