Hi all,

ive been having problems with my R33 lately, about 3 months ago my CAS shit itself so i got a new one and it was fine.now a couple of weeks ago it started doing the same thing , cutting out while driving, when at lights stationary even when warming up it would idle then die.

So, i bought another CAS as i thought this was the problem again.I took my car to Race Pace for a cam gear install and to chack out the problem.

The car was there for 2 days and never missed a beat so they couldnt rectify it but they did put in the new CAS just incase.

NOW, this morning i went to start my car and nothing happened, it wont crank over at all

CAN SOMEONE HELP?

sorry guys

it sounds like it wants to start but wont turn over. when i asked the guys at Race Pace they said it was unusual to have 2 CAS shit them selves within 3 months and that it might be another problem like an AFM. could it be something else?

The usual would be check to see if theres fuel in getting in there, afm if its stuffed im sure would cause over richness, But best bet is pull the plugs to see if they are wet from fuel. Next would be see if you have spark you know how to test that? and in specifics do you mean you turn the key and the starter just keeps winding over trying to start? im sure thats what you meant, also doesnt hurt to check fuses especially for things like the injectors fuel pump. also another thing if the plugs are dry, just get a friend undo the return line at the fuel rail and get your friend to just turn it onto the "On" position not start it to see if the fuel pump is sending fuel? Thats a few things there for you to try out Hope they help But generally if the afm "is" stuffed you should atleast get a beat out of your engine im sure

thanks for the info mate ill check all that out, as its probally best to start eliminating all the little things first. its just so hard to comprehend how the problem comes and goes, one day its fine the other day its not and now its just looking pretty

Give it to a workshop and leave it with them till it fails. Then they can use the appropriate tools and diagnois the problem properly. You really need a spark tester and a noid light on the injectors as a minimum to eliminate the CAS and determine exactly whats missing from the equation.

the cam cover is still on, but the problem was there before the cam gear was even put in,even after i picked it up from the tuners it was fine till this morning. Race Pace is highly SAU recommended tuner with high experience with skylines. I would think he followed correct procedure when installing the cam gear.

Well i guess i got to put it on a tow truck and take it to them if there is nothing i can do to fix the problem.

If your car isn't starting and your battery isn't dead there is 3 main things to look out for...

1: check for spark

2: check for fuel supply

3: check compression

If you find all 3 of these things are fine, then start checking to make sure sensors are plugged in and not faulty, for eg throttle position sensor. If compression is fine but there is no fuel or spark, check CAS. If you are in Sydney and need assistance, drop me a pm and I'll give you a hand!

      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
