    ok...that eliminates fuel pump and assocaited circuitry......


    what about spark......?

    ignition modules can go like that......they work fine...then you switch the engine off....and they never work again........



    pull one of the leads off and stick a sparkplug in it with a large gap......
    sit the plug on something metal so it earths out and crank the engine over.....
    see if you get a spark......


    if youve got fuel......you may not be getting spark.....
    you can also pull a plug or two out and see if they are wet with fuel after cranking.......

    another indication of them not firing......

    May seem like alot of Qs but the anserws tell alot , ta .

    Do as Tony says and see if you have spark at the plugs .

    If no spark at the plugs take the coil lead out of the dissy cap , remove the cap .

    This bit can bite if you don`t take precautions ( insulated plyers , plastic tongs , etc ) ................ hold the coil lead end 3/5 mm off the rotor arm middle and crank the engine , if you get a spark the rotor has probably failed , crook coil or wires will give the same .

    The module on yours if factory should be under the coil and the are generally less likely to fail than the later dissy mounted ones .

    If you need to test this , can tell you how , slightly different to dissy mounted .

    Has any work been done to the car in the last month ?

    I know you`ve already answered this but are you sure the battery is fully charged , some cars are more effected than others but a half charged battery can have a big effect on how or if an EFI will start .

    I know it seems like a minor thing but it`s not .

    Cheers
