    Failed to proceed, ignition problem?

    So the old girl ground to a halt today, was running sweetly then without warning no power, engine died. Had the indignity of a ride home on the back of a truck. After a bit of investigation there is no spark. I have followed the test procedure via Rave and all seems well. Plenty of power in the battery, 12.5v at +coil, 12.5v -Coil. The complete Dizzy was new 3 months ago. (gas and Petrol all fine) Still no spark. Any other test I can do to point a finger. I have never had experience of a coil going bad so dont know the effect, would it be so sudden? If I get no more Ideas I will go for a new coil, Is there a special type or is a generic one from Repco or the like suitable?
    The vehicle is a 93 Classic

    it's a long embarrassing story but just double check your coil-distributor lead. it may have failed, (or be unplugged beneath one of the shrouds- i did say embarrassing, i spent DAYS looking for this once!)

    Does it have a capacitor in the dizzy? These can drop their bundles without notice and nothing short of replacing it will get it going again.

    Good luck with resolving the problem.

    If no spark there are several possibilities.
    1 Most likely for sudden loss is that a lead has somehow lost continuity by falling off or fracturing Can be at dizzy/coil etc.
    2 failure of ignition module on the side of the dizzy. These usually give warning by failing when hot then OK when cold.
    3 failure of ignition pickup in dizzy.
    4 failure of coil but again usually gives indication.
    5 less usual but possible- rotor has failed to earth. This happens mainly with aftermarket rotors and usually quickly. Fix is Lucas brand rotor even if it costs $40.
    6 wire to ECU from coil has failed. This is in the loom that goes to MAF then to the coil.

    Thanks for the info,
    The complete dizzy was new less the 1000k`s ago. I still have the old one which I might swap back to eliminate it. Do yo know of a test procedure for the Maf wire you mentioned, also still dont know if I can fit a generic coil

    You must fit a coil compatable with the ign amplifier. There was a thread on this a couple of months ago so have a look.
    which coil??????????????????????? d1 v8

    Just check if the ECU wire is attached to the coil terminal. If all else fails you can check continuity at the ECU plug and coil end , but that is far in the future.

    Update,
    After testing all connections and following tips and Rave I decided the cheapest 1st option was to change back to the old Dizzy which I new worked. Bingo firing up on all cylinders.
    Maybe a lesson here, the original dizzy was only changed because the Vacuum unit was kaput, I purchased the complete dizzy from ebay for less than the cost of a new Vacuum unit, about A$130, from the UK. It was not a genuine Lucas part so probably made in China or the like. Obviously not that good or I am just very unlucky.
    Anyhow now I have the new Vacuum unit in the Old Dizzy and all is well.
    Now for a few beers.
