Hey all

I have a serious problem here and I just can't figure it out and advice will be greatly appreciated.

I have a Cefiro A31 with an RB20DET. Less than 2 weeks ago I changed the battery (this is the third

battery since April ) a new maintenance free was installed. A few days after the car was stalling in traffic

and it just couldn't start so it was towed home.

When I did the ECU diagnostic test I got code 13 so both engine temp sensors were changed, I bought

new OEM Nissan sensors. After resetting the ECU and changing the sensors the car still cannot start

and the battery is dead. I did the ECU check again and got code 55 = No Error.

Can anyone advise what can possibly be the problem ???

Cheers

I had a very simlar problem with the misses car doing the same thing. After 2 new batterys and 4 weeks of diagnosing the problem, it ended up being the stezza causing the battery to drain flat. The Stezza worked all good with no problems but when you put a volt meter on it to see how much current it was pulling with it just being on standby with no ignition key on, it was pulling stupid amps from the battery killing it.

Im not sure if this is any help but do a test by disconnecting the + battery lead and by putting a multi meter between the + battery terminal and the battery lead with the ignition turned off and all doors closed because your interior light will draw power dont forget. You should be able to set your multimeter to show amps and then know what its drawing. I belive that it should be no more than 0.08 or 0.1 of a amp. If it is more than this, you have a problem or short somewere which is killing the battery.

Alternator is the only other thing you may wana check. It also may have a problem not charging or it has a short too. You just dont know till ya check it out.

If you havent got a multimeter, get one mate coz they are a very handy tool to have. If im not even close to what your asking, just say :P

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
