    Default my engine bay caught on fire: what next? :)

    well it looks pretty minor, i started her up and put my stereo in, was reversing out when i heard a loud bang, sounded like when you turn the bbq on.. next i saw smoke comming from the little washer spraying thing, and knew straight away what was happening... so i quickly turned my car off, and soudned the horn, to get the old mans attention... he ran out with a hose i popped the bonet and we outed the fire..

    but, the question remains..
    did i screw anything?

    it looks like the fuel line (near the pump) was ruptered, guessing this is the cause, it must of been dripping over night.. it was the back of the engine, so was pretty much up the firewall...

    no visable paint damage, because of the uncover bonnet protector (thank god) but the fuel lines are pretty knackered. i'm going to change them all tomorrow and my fuel filter. Also it melted some of the engine wiring harness, not sure if it went through the insulation on the individual cables... is there anyway i can tell?? or will i have to drive it and hope nothing starts to die...

    the engine bay was on fire for about 2minutes, could it have caused a head to crack when we hit it with water? we sprayed the bonnet and not directly onto the engine.

    bit of a shame... when i finally get some money together to do something to it, this happens..

    i suppose thats life! any suggestions on where and how i start troubleshooting what could be hurt?

    i would think wiring would be 1st thing i would be checking, use a multi meter to make sure you don't have any shorts. Also i'd check over your plug leads too just to make sure the fire didnt harm them, really i think the main thing the fire can damage is the electric's, and hose's etc. You were only backing out of the garage so i doubt very much you would have had the engine hot enough to do damage when you put the water on, i wouldn't be too concerned about that.

    Mark,
    With your wiring, I'd seriously think about changing it (engine and maybe battery), becasue the ECM uses resistance readings from the sensors to make it's calculations. One of the first things that fire does is heat the wire and then the resistance of the wire will go up possible giving incorrect values to the ECM. Also remember that your dizzy is at the back of your engine. Imagine pulling up at the lights at 10pm at night and then your car stops because the wiring going to the dizzy was damaged with the fire. Can you imagine the hassle!

    I would also change all the fuel hoses within the vacinity of the fire. You don't want a larger fire that does a lot a damage becasue you didn't change 1 or 2 hoses. Just remember they carry fuel, and that's how you want them to stay.

    Another thing I would check is the throttle cable. Last thing you want is to put your foot down and get a throttle stick at full noise!


    Good luck with it, hope the damage is minimal.

    thanks guys, the engine loom doesn't look to bad, at $180 for an engine loom i might chill on that for a bit, and just tape up the wires as they are at the moment, just incase something is showing..

    i'll just fix the fuel lines and fuel filter now, and see if she fires up..

    where could it have happened from? Its got me stumped..
    the car had been started for a few seconds maybe 30 or so. Everything is pretty covered up, electrical wise, but its sparked from somewhere.

    with the wiring try just pulling back the conduit around the loom first to see if anything underneath is melted. if theres nothing visible it's most likely it'll be ok. i'd be more concerned with the body loom. that would be harder to change than the engine loom. stuff like the alarm, indicators, headlights and whatever else is in there. not that it's very complex, just a bitch to change i'd imagine. like everyone has said change all your hoses, you might aswell do all of them while you're there just for peace of mind.

    lucky it happened at home and not in an intersection or a carpark! why would the fuel lines rupture? were they old and brittle or could there have been too much pressure in the line for some reason? or a loose hose clamp?

    too hard to tell now,

    could of just been a loose hose clamp... under pressure it might of been just to much for it!

    I'm guessing the fuel caught fire on the exhaust manifold/extractor.
    This should highlight the most cheapest and important accessory for any car, a $20 fire extinguisher.
    Maybe time to hook up a group buy for us all Mark?
