its around halfway down the block,at the back of the engine,jack up the car,and crawl under for a look.I dont know, could it? Anyone clarify? Not even sure what exactly the knock sensor looks like and how to plug it back in
dont forget to put axle stands under the sills for safety!!!

Cheers dude, dont have axle stands so ill just brave it with one jack either side.
Anyone else clarify whether the loose knock sensor wire would be a possible casue if this touched the chassis etc.. ??

safety first
@Black_Mamber: i'd second that; a knock-sensor wire break or short can cause a multitude of problems so check it out. it will only take a couple of minutes.
& secondly, don't take a chance with jacks only. get some blocks, planks of wood, you can even remove your front tires to put under the sills as a safety measure in case your jacks decide to take a break from holding the car up..
we need you alive to tell us the result of this, not crushed by your ep..

Thanks pal, I'll try get some axle stands. Appreicate your concern.
im just hoping that pait work is still looking good dude. im paranoid now mines gunna set on fire
lol paint work is fine mate, it all sounds worse than it is to be honest. Youll be fine dude, I just have really bad luck with this car.... but im not gonna let her beat me
I'll get there in the end

UPDATE
Tackled the car on Sunday with a mate whos pretty decent with electronics.
Found that all the earths were very shoddy, and the earth the shorted out on the gearbox has got water in it, so the copper oxidized and just fell apart.
So, Bought all new earth wires, proper connectors, cleaned up all earth points and made backup earths around the bay incase one ever fails. Looks so much better and all wiring has been covered in that wire cover stuff.
Re-connected the knock sensor which was a bit of a mission. Looks like its just randomly broken away from the connector, so we had to re-wire it in using another connector and holds in nicely now.
But......
Front drivers side brake lines have been damaged as a result of the fire and are leaking when i applied the brake.
Anyone know where i can buy just front braided lines? as backs arnt needed.
Still wont start. Everything tested out ok on the multimeter apart from the battery dipped down to 7 volts when we tried to start the car, so the car just made a clicking noise. My mate thinks the battery is goosed (few dead cells) from when the car turned to live when the earths died out and as a result has not got enough power to start the car. It still didnt want to start, or even sound like it wanted to start when we had jump leads connected to my mates civic while the civic was ticking over.
I have a warranty on the battery so that is going back to halfords tonight to change.
If its not the battery (which my mate is pretty adamant that it is), he thinks it could be the starter motor which could have been affected.
Any thoughts people?

battery or starter
if when you tried to start, it was making a rat-tat-tat-tat-tat kinda sound then that's defo your battery not having enough juice to crank it, so it just makes the fast-forward cluttering sound.
i'd say after you've gone over all your wiring again, swap the battery and re-try it. it will work. all the best with finding your braided lines.

It wasnt making that usual rat-tat-tat sound like what i thought it would do. It just makes 'one' clicking noise when i turn the key, like the starter motor is ready, but nothing’s happening.
Ill change the battery and go from there.. Just eliminating each problem one by one.
Thanks for your reply btw dude

problem elimination
good one on the problem elimination route/method. will await your response and hopefully help from there. just curious, when you turn the key and hear the click, do the dash lights (or any other accessories such as lights that may be on at the time) get dim as if they are fighting with something drawing heavy current.. (the starter in this case)..? ..or is it just another summer's day..?

Nothing seemed to dim really (tested the voltage when heaters were on, lights on full etc..) the battery voltage only dropped dramatically when I tried to start the car & gave out that one click noise, nothing set on fire this time though as its all earthed up proper nice.

Hi Texx,
Thanks & no i havnt tried that. Not too sure how to go about doing that tbh.
Changed the battery for a brand new one last night and its still the same. Just clicks once when you turn the key and the lights around the dash dim slightly.
So fingers are pointing at alternator &/or starter motor. How would i go about testing if the alternator is goosed?
At least ive ruled out the battery & sorted all the earthing out up to scratch... on to the next possible culprit
Brake lines are on their way to mine so im gonna fit and bleed them at the weekend.

electrical prowess
if you are feeling sufficiently electronic :haha: then you can wire up the starter and alternator and test them. remember the alternator is basically a motor than works in reverse. by being spun, it generates electricity. it can also be fed with power and it will still spin..
if not, just get proper working ones, plug them in and see if your problem goes away.
about the fuses, yes, i believe you should go through all your engine bay fuses. here's the fuse-box schematic to help you through this procedure.
there are other fuses spread around the car but doubt these will be necessary in this particular instance of troubleshooting..

UPDATE
Jacked the car up today, got some axle stands under there and continued to hunt for the fault of why the car isnt starting... We started by taking off the starter motor and checking that, and the result when we took a look at the teeth in the motor, they were all chipped and fucked.. THe electrical fire problem somehow tripped the starter motor and it span when i was driving, which is why i heard all that crunching metal when i pulled over. The engine starts fine when turning the engine over by hand. I just need to order up a new starter motor and switch them. Also managed to change my brake lines from the burnt ones that are currently on there.
Will update again when the motor is fitted

flywheel teeth?
@Blak_Mamber: good one on finally finding the culprit. i would imagine the starter teeth were totally chewed out and some damage may have also been transferred to the flywheel. that's worth checking too imo. i know it's a lot of work to pull out the trannie and take a look but it's worth it. if this may be too much work, you may at least want to get a bright torch (and maybe a mirror) and a mate to rotate the engine by hand slowly as you peek through the starter hole to check the flywheel teeth.
no point swapping the starter only for it to also be chewed out by the bad teeth on the flywheel..
