Ok... After a year of owning the car with no problems whatsoever...i have finally came across one.

Problem that i'm having is -- the battery seems to be draining heaps quickly.

i have not driven my line for 5 days... so i assumed due to the cold weather..of course we get that awful cold start..i tried starting my car-- no luck.. till it just pretty much drained the battery. ( u get that "click click click " noise everytime u turn ignition on )

so i assumed battery was dead..i had it jump started and it went ok..started.. took for a 30min drive around town.. went to the supermarket for an hour.. when i got back.. the darn thing wont kick in.-- dead battery AGAIN.. so i jump started and worked OK. -- this i assumed the battery needs replacing as i had it ever since i bought it.--- so i got me a new one.. one click and the car started.. no problem. -- now went home and tried starting the car -- 4 tries and NO LUCK.. kept trying till i hear that " click click click " noise -- battery dead again.

i dont get it.. its fine when i jump start it.. starts pretty easy... but when i leave the car off for just 2 hours..it wont start.

I ruled out the alternator coz i had that problem with my previous car and the symptoms are not the same.. the car runs well..using aircon on / stereo and head lights.. nothing i know of that signs of alternator problem.

could it be the starter motor ? :confused:

Anyone who had the same problem and would be of help would be appreciated

thanks.

If you've got a multimeter, put it in series with one of the battery leads and measure the current draw with key OFF. Should be close to 0. Anything more than 1/2 to 1.0 Amp will drain the battery pretty quick.

Is the battery voltage around 14v with the engine running?

If it jump starts OK, i'd doubt it will be the starter. Sound more like a lack of voltage problem.

hey does it just click or does it crank really slow??

plus double check the starter & battery terminals also you may have a volt drop on the switch wire to the starter

when you mean its flat are you sure its flat like are you head lights dim??

will your radio work??

if they do well could possible be starter related

just went and check the boot light and it was fine.. doesn't stay on.-- all terminals are fine.

and yes.. i can still play the radio / stereo and some lights.. but it just wont crank up.. and when it does.. it is slow.

could be a voltage drop.. dont think its the starter as it fire up fine when hooked up to another batery.

now.. how to fix this voltage drop..??

      Crank/No Start - R32 GTR Chassis with R34 RB26

      By 89GTR_VA · Posted

      Apologies for the long post, but needed somewhere to lay out the entire timeline of events and actions taken:   I've got an 89 GTR with a R34 RB in it. It's been running great all year, driven probably 500KM in the last month. It's not my daily driver, just a weekend fun car.    Build info: R34 RB26 - HKS 2.7 stroker kit, HKS adjustable cam gears, HKS turbo upgrades, Trust intercooler, R34 factory DENSO 440cc injectors, JUN chipped/tuned R32 ECU. All of this work was performed in Japan back in 2019.    Thursday 10/2/25 - It's a nice day and decided I'll drive it to work, I start it up in the garage and I notice it took a few extra cranks and sounded a bit funny. I figure maybe it was just because it was a pretty chilly morning. I pull it out into the driveway to warm up a bit before leaving. As I leave the driveway, it feels very off and sounds like a misfire. I pull it back in the garage to deal with after work and take the daily to work. I was able to diagnose it as a cylinder 5 misfire with the old spark plug test (unplugging each plug until a sound change with the engine running). I take off the whole ignition system, ignitor, plugs, spark. *Important note, it is still on the R32 ignition system with the separate ignitor system. I test each system with a multi-meter and nothing presents as a smoking gun. I put it all back together and it starts up no issue. I go ahead and order the PRP R35 ignition conversion kit. It should arrive today (10/13/25)   Friday 10/3/25 - Another nice day, car starts up great and drives great all day. Very pleased that everything seems to be OK   Sunday 10/5/25 - Decided I'll take it to play some golf, load up and drive to the course about 25 minutes away. Drives wonderful the whole way there, I pull in the parking lot and the engine completely comes to a stop. I do not recall if it sputtered at all, but just remember all of the sudden the engine was off. I roll it into a parking spot, try to crank it back on and nothing.  It'll crank and crank and not even try to start. End up getting it towed back to my house and push it up into the garage.    Items I have checked: Fuel in the tank Fuel Pump relay Fuel pump fuse  Spark Plugs & gap Coil packs Ignitor    I know the cylinders are getting fuel as the plugs smell like fuel after a start attempt. I tried spraying starter fluid into the manifold and cranking and not even a sputter.    I decided to do the live CAS test (removing the the CAS, ignition on and spinning the CAS stalk to see if the injectors pulse and spark is active). All of the injectors were pulsing and I have spark at the plug. The half-moon end of the CAS did seem very loose, I'm not sure how much play is supposed to be there, but it was more than I expected. There was no in/out play of the shaft, just the tip end that is pinned on had quite a bit of play.    CAS Play video   When I put the CAS back in, I stupidly did not re-time the engine. I know I need to do that tonight, however, I do not think it will start given it seemingly was not the issue. My plan is to do the PRP R35 coil kit and retime the engine at the same time.    I plan on ordering the Haltech Nexus Plug-in ECU once they are available again, but ideally would like to get this sorted before firing the parts cannon at it and potentially adding more variables.    Anything glaring that I am missing here, I'm a bit at a loss?

      Get it on a dyno. Get something logging Consult. Run it up and find out what is causing it.

      Freddy Plenum vs Genuine options RB25

      By BuiltNotBought · Posted

      Looking for a plenum for rb25 de+t neo  Not looking to push much power maybe 300kw at the wheels, is there much difference in flow for Freddy “Greddy style” compared to original Greddy or options like Proflow or Otaku garage?    I won’t be porting the de Neo head for now as I think it’ll be fine 280-300rwkw but appreciate the help and any experiences anyone has between them and any advice. Thanks  Looking at this plenum for now below
