Hi guys, sorry about the essay

Got an interesting problem and i'm sure it has a pretty easy solution and i'm just not thinking of it, so here are some details.

I have lost my licence so haven't been driving in the last few months. My car has been driven by my mate (with me present so nothing unusual) anyway it hadn't been started in about 2 weeks.

The car has an auto start, so i figured i should just turn it on and start it while i was doing stuff around the house, anyway it started for about a second then stalled (unfortunatly it's not that uncommon with the auto start if it hasn't been started recently) anyway it tried to start again and wouldn't fire.

I tried pulling the spark plugs and cleaning them and it still wont fire, it nearly gets there but wont turn over. The spark plugs were changed about 2 months ago so i only cleaned them up with a wire brush. a few of them were pretty badly covered but cleaned up ok. at least 3 were pretty good looking.

Although after trying to turn it over i pulled one of the plugs and it was pretty dry from memory.

When i go to start it i can still hear the fuel pump priming, and can hear it running into the engine bay, so i don't think it's that.

I havn't changed the timing or the CAS so i have just checked that the plug is in correctly, seemed ok.

i have pulled all the coil packs and had a look. i couldn't see any fractures in them but i doubt i would've seen them anyway.

i checked to see ifit was getting any spark by trying to hold the coil pack and turn it over. At first I thought i saw a few white sparks, then what looked like an orange. I also recieved a small jolt from the coil pack. (Could this mean it's cracked?)

The mods are basically:

Haltech e11v2 and all sensors also it's MAP

boche 040 or 044 i can't remember which one i ended up putting in (it's in tank)

nismo 740cc

sard fuel reg

adj cam gear

fmic

they are the mods that are associated with it that i can think of.

i have checked any connections i can think of.

I have a few theories but not sure. They are;

Busted Coil packs. (but why wont it turn over on 3 or 4 cylinders, surely they can't all have gone at once?)

Busted CAS. how common do they just stop working for no reason after not being touched?

Faulty ignitor module?

Faulty fuel pump even though i can hear it

blocked injecters?

faulty ground for the coils

There were a few other theories i had but can't remember at the moment.

Any advice or ideas would be great, or any other symptoms or ways to test any of my theories would be great.

or if anyone has a set of coil packs i could try that would be good. i just don't understand why it woldn't just fire and run on say 4 cylinders unless there is a guard against that with the ecu?

Thanks guys

I'll have a look around and see how i can check the sensors.

What are the chances it won't let it run on 4 or so cylinders?

This might sound stupid but I had the same problem with auto start once. When the car starts and turns off real quick it doesn't have time to burn all the fuel. Try pumping the accelerator all the way down then slowly release it and turn her over. Should clear the lines of fuel.

Yeah i thought about that and it didn't seem to help. It wont turn over no matter how you try to start it. Not sure if i mentioned when testing the spark it didn't seem consistent. I meanlike after a while it didn't look like i was getting a spark anymore. Plugs are clean enough, o i assume it's coil packs, ignition module, or something else associated with the spark.

Does anyone know anyone who might be able to lend me some known good coild packs so i can test it. Also does anyone know why it wouldn't jus tturn over on 4 cylinders for example. They can't all be screwed. This might lend it to being th igntor module?

So i thought i would take out the ignitor pack and try a new one of them. Well i thought it may have been relocated somewhere but looks like i don't actually have one now. The car is a '95 so i'm wondering is it possible that i have series 2 coils where the ignitor is inside the coil and how do i check this? thanks guys also anyone have some coils i can borrow?

      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.
