Hello, I have an aftermarket alarm and immobiliser fitted to my r32 gtr, and I believe the immobiliser is consistently stopping me from starting my car, If i havent driven it for any longer than 2 hours there is a chance it wont start, or will take about 15 goes to start, When I say goes i mean turn the key remove it and repeat, I thought it was my battery but the voltage over a week only fell from 12.35 to 12.25, please help its really annoying

Hi,

When you go to start the car (turn the key) does the engine crank? Or do you get nothing at all? When you say it takes 15 or so goes to start the car, are you pressing a remote? or swiping an immobiliser tag attached to your key ring? I ask this because the R32 does not have a factory immobiliser as standard, so if there is one, it would be an aftermarket one, which means there should be a device to disarm the immobiliser when it has armed (ie remote, Transponder Tag, Touchkey Tag etc). If you have nothing but the Nissan key and it takes you 15 or so goes to start your car by removing the key and retrying each time leads me towards your starter motor and the first question I asked. If it does not crank at all or you hear a click sound when you go to crank then either the trigger wire to your starter motor solonoid is not make good contact and needs to be unplugged cleaned (light sand paper job) and then plugged back in. Easy job! If it makes no difference after cleaning the contacts of the trigger wire then it may be the starter solonoid itself. Over the years they can develop dirt and grit internally which can cause the solonoid to be stuck or jammed. To test this you need someone to be at the key testing to see if it cranks while someone else taps or hits the starter motor solonoid area with the handle end of a hammer (preferrably a hammer with a rubber grip or wooden handle). If it decides to start cranking as a result of this then remove the starter motor, pull it apart and wash the internals with a liquid solvent (petrol and a paint brush) dry it up, put back together bolt back up to the car. OR have it reconditioned by Auto Electrician.

If it cranks over but does not fire (start) then it is another problem all together. So you would have to get back to me on that.

thank you for the reply, the car has a button immobilser in order to open and start the car you need to press it, if you try and start it without pressing the button the alarm goes off and this red led installed on the dash flashes. When I bought the car last november it was meant to have had a new start motor installed with the rebuild but who knows.

The car doesn't crank at all when I do it, but I do hear the clicking noise!

      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.
