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!

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
