Guys,

I'm hoping someone can help.

Today I disconnected the battery so I can install a new fuel pump. That took three hours so the battery was disconnected for that time.

When I reconnected the battery, the car wont start. That is the pump isnt priming and no lights on the dash when I try to crank it.

The alarm light doesnt even blink like it usually does, it is a three point alarm. I have disconncted the alarm's black box, and tried another battery.

I have also tried disaraming the alarm from the alarm manual

Has anyone ever experienced this? Any help appreciated

Thanks

Hey man.

Ok first make sure your battery connections are on VERY tight. Believe it or not, if they are'nt tight the car may not start. So do that and turn the key two clicks and see if the lights on the dash come on and your fuel pump turns on. If so, the car should start up fine.

If not, check all your fuses in the engine bay and inside the car and use a test light on either side of the fuse to ensure one or more is'nt blown. You will probabley have to try them all and that does mean turning the key a click or two (depending on how the fuse is set to come on) to do this.

If that all checks out, well then you have a worse problem but lets not think like that yet. Try this and let us know.

Good luck man.

Cheers >_<

Yep just checked the battery connections and tightened it all and checked all fuses too. The ones in the boot, under the dash and in the engine bay, none blown

Whats worrying is that the dash lights dont even come on. The alarm light isnt blinking so I dont know what the status of the alarm is and I need it to blink to enter in the alarm override code.

Is the alarm cutting the ignition switch and electrics? Theres no lights on the dash at all. The radio, water spray, headlights and mirrors work but it wont allow me to wind my windows up.

That definitely sounds like a fuse. If you disconnected the battery and accidentally tapped the terminal with the cable, that could have been enough to blow one or more fuses.

As sidewayz said - use a test light to check continuity. If you haven't got one, a pair of pliers and 20 mins to check each fuse

Ok I'll pick myself up a test light tomorrow and do a more thorough check. I only pulled out each fuse and checked it by eye so far. i hope its not something more serious

Thanks for your help guys

Could there be any more possibilities or anything I can check?

Primordial, it turns out I did have a burnt fuse, its the one in the boot, third one from the bottom its a 10A !

I replaced it with a spare in the fuse box under the dash but its still having the same problem!

Any other fuse boxes in the car? so far I've checked boot, the one in drivers side dash and the the one in engine bay near washer bottle.

Edit- found out the burnt fuse was for rear tail light. I checked all other fuses too with a multimeter and its all fine...

Problem has been fixed, it turned out that my alarm was totally farked.

It was cutting off all ignition in the car and wouldnt come back online when the battery was reconnected

Auto electrician came to rewire it back to bypass the alarm and its all good! (except the alarm going shopping for a new one now)

      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.
