Ok i was heading north up the hill to the harbour bridge and the engine just stopped. Cranked for a bit, restarted, got to the top of the hill then it died permanently. I assumed it was fuel pump, have swapped it with a sard (which i can hear priming ok) but it still wont start. Checked CONSULT - no errors.

What do i do now? What's the easiest way to check for spark and injector operation. I can't hear the injectors over the engine cranking noise, and i don't have anyone to listen for me.

Ok, i pulled the CAS, spun the shaft and the injectors clicked. So i guess that means its fuel pressure or spark.... I'll check the coil transistor is putting out 9V to the coils next i guess...

Sounds like a CAS issue.

thats what i was going to say, if you have a dodge plug or injector car will still run, just like a bucket of puss. if your crank angle sensor is playin up car wont fire at all as far as i know. checking it.... hmm replace it?

Fuel check? - Pull the plugs to check for wet electrodes

Electrodes are dry....

Ignition check? - pull a coil and plug out, allow to earth on cam cover. have sum1 else check if the plugs sparking

Yep i have spark. Didnt look that strong but it was in direct sunlight.

I've pulled the fuel filter, and blew it out the inlet to see what came out. The petrol looks cloudy. Maybe it is/was blocked so i'll put it back together to see if I can start it. I had no luck getting new filter tonight. Repco/Auto-one havent heard of late night shopping.

Ok update: I ran a temporary wire from the the battery to the fuel pump and could start the car, so i know its definitely the fuel pump power circuit. The sound i thought was the fuel pump must have been something else....(HICAS? ATTESSA?)

After tracing the wires it appears i have a problem with the "fuel pump control modulator". I never even knew i had one...still dont know what it does. Anyway, i found one of the plugs was burnt so I opened the unit and found a dry solder joint. Re-soldered it but is still doesnt operate the pump. I guess i'll get another one from a wrecker and swap it out.

The other thing i like to check is the fuel pump relay - does anyone know which one it is?

fuel pump relay is located next to the driver side taillight behind the boot trim.. we have similar issues.. mine i had to earth the relay with new wire.. traced it to the FPCM on the back side trim and made another earth there.. havent opened the unit up like yourself to check the damage but sounds like a good idea..

      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.
