    Default no ignition spark

    After a fiasco involving me stripping the spark plug and snapping a coil its all now back together but now it cranks but no spark. could something have fried? (I did disconnect the battery). It's taken me a month to get the car in one piece (travelling) and now it still won't work. Any help would be appreciated.

    Its the VZ by the way

    how do you know its got no spark?, are you assuming, or have you tested it, each coil runs seperate, so it should fire some

    sorry for the premature diagnosis. I really haven't checked for spark. What would be the best way?

    yeah went and done that, all seems well. will check again under daylight. I gave it another run and it seems there is no fuel getting to the engine, i've cranked it for a while to no avail. Would sitting for a month drain all the fuel back to the tank and take ages to prime?

    I the 'lock' indicator in the binnacle still flashing whilst
    you are starting?
    Check fuses, relays etc.
    I'm not afraid.

    "i havre had the same issue once or twice, the deal with this is lack of fuel, the fuel pick up has no fuel in it, well the computer thinks that anyway and wont allow the engine to spark, i believe it may be something to do with air in the fuel lines. But a splash of fuel $15 or bout 10L will normally get the car to respond and spark, or shorting the relay will make it respond.. "

    I copied this from another thread. Could the fact that the car is parked on a slope, (back lower) be stopping the fuel from taking up? there is about half a tank. the lock sign goes away. I got it to sputter a bit so fuel is my guess. Any input would be great.

    with a new battery and lots of cranking the car now starts. But. now there is the sound of something rattling around inside and a very rough idle. God I hope nothing fell in when the manifold was off. I'm pretty sure it didn't. its a two per second sound, maybe something fell behind and on to the front of the gearbox. out comes the torch again

    when you say, spark plug broke,? what exactly broke, id say its very probable something has dropped into the cylinder,

    insaying that though, does the sound come from the very top of the motor? and does it come from where near you had problems with,

    I didn't witness the drilling out of the plug but it was done by a highly recommended professional. It was then obviously tapped and helicoiled. It sounds like two solid metal pieces connecting, a little too much like a socket for my liking. What is down the holes the intake manifold sits on? it stops and starts so I'm thinking if it went down the plug hole it would be faster and non stop. Please correct me if wrong.

    yes it would, and yes if something was down the intake runner sitting against the valve yes it would make the irregular rattle, and willl increase with engine revs, although i wouldnt recommend revving it if there is something sitting there

    cant see anything in there. does the runner go straight down to the valves? could it have gone under them with the airflow? If yes to number 2 is it a full engine pull apart?

    All clear. found a 13mm socket behind the engine that was vibrating against a metal plate. After my repeated issues the manifold gasket now has a tear off one of the runner rims. Would this cause a rough engine through the rev range? will it damage the vehicle driving for a few days like this as I'm sick of putting the missus out driving her car

    P.S. Thanks andyman for the constant help

    wont damage the motor if the gasket is cracked, but may make it idle ruff when the motor is producing vacuum, if it does leak

    changed the gasket with a metal one. (I could only find genuine, $44) and it's heaps better but still not right. I'm guessing that the manifold and runners should not be all oily as this would mean the TB and MAF would probably be the same way. What do you guys recommend to clean them? Common sense says not a hose.

    Mine has oil around the inlet manifold/plenum gasket.
    Probably from the PCV system.
    Clean TB with carby cleaner and MAF with electrical
    contact cleaner or expensive MAF cleaner.
    I'm not afraid.

    i'm sure aviation grade contact cleaner courtesy of work will do. the runners and manifold are literally caked with burnt oil. Would carby cleaner be alright to clean the whole manifold? bit reluctant to add a potentially flammable substance to an engine inlet. Is this just a natural occurance, because the cars been running rough with the bad gasket or a deeper problem?

    sorry to keep going with this but I'm trying to also add some info for the alloytech. More and more members are going to start to get to 120k in their alloytechs and may notice these same issues.

    If there's that much oil I would remove the
    plenum and inlet manifold and clean them
    with kerosene and a brush then dry with a rag.
    How were the condition of your plugs when they
    were replaced?
    I'm not afraid.

    Applied gasket sealant and wiped out the throttle body. For the first time in about 6 weeks the engine is purring, just like it was before I touched it in the first place. While it is a pain in the arse that it went wrong I now can remove an inlet manifold in about 2 minutes.

    Do you think the gasket sealant makes a diiference?
    Just think of the cost of a Holden technician removing
    those manifold's!
