Car Won't Start

Ok. So I was driving on Saturday, and when I gave it a bit (under full boost = 10psi) it would hit a wall kind of like boost cut at 4500rpm for 5 secs then kick into boost again.

Checked over a few things that I thought could be the problem.

1: cleaned afm and plug.

2: tightened intercooler piping and checked for boost leaks.

Nothing worked

Was running and driving fine apart from when I put my foot down.

Then this morning I went to start it up and it wouldn't kick over. So I got a new battery since the one I had was a lil old, put it in and still no dice

All the belts are moving and its just on the point where it wants to kick over, which makes me think it could be the starter motor??

Car was also recently tuned.

Car: Silvia

Engine: Rb25det

Mods include, splitfire coilpacks, turbo back zorst, Apexi avcr, apexi safc, platinum plugs, intercooler, brass button clutch, nothing major.

Any suggestions would be great.

cheers, Ben

So it's cranking, just not starting? If that's the case, it wouldn't be starter motor. To eliminate that, try jump starting it. If it starts, that'll be the problem. It still would explain the problems under boost.

I would have said coil packs, but you've said their spitfires so that wouldn't be it. Have you had any work done to the car recently?

Check the ignotion system. Is the car getting spark? Is it getting fuel? Are there any plugs that have fallen off? All the vacuum lines attached? I'd check all these first, and then take it to a mechanic.

You need air, fuel and spark to start an engine. Seeming as though you havent listed an aftermarket fuel pump (possibly meaning your still running the 15 year old standard one) under mods that would be the first thing I'll be checking.

try checking the coilpack wiring loom as this can deteriorate overtime which will also cause the car to not start apparently some people who replaced the coilpacks didnt realise that while doing it they might have damaged the wiring as overtime heat caused the wiring to be crispy and would crack easily

Changed the ECU and ignitor module yesterday, neither worked, there was no spark at all. So the problem lies between the module and ECU (as said above, in the harness somewhere).

My thoughts, it could be the resistor?

IS anyone an auto electrician on here or know someone that can come to me as the car doesn't go. For cash :P

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
