    What air flow meter you got on it?
    Flapper or hot wire?

    I wouldn’t think much difference with the 4.2 heads. But have you checked the specs and compatibility (I don’t know)
    Did it run before and do you have old heads?

    If there's a spark I would advance it till the engine locks up when you try and start it, (like flat battery) then knock it back a bit. if that dont work it's probably fuel but easy start should make it fire.

    Mine had 4.2 heads, it was on su's , another thing could be condenser if you're on points

    plus one re condenser and apparently modern ones are sh!t made in China, But if he bought a new dizzy it is probably a contactless. It ought to be, eliminates a whole world of probs and they are cheap enough and reliable enough now. Just needs one more connection.
    Now I'm wondering if that is the problem.:eek:

    My 4.2 went down for weeks until I replaced the coil and condenser.

    Checking back to his first post he mentioned the "ignition module" on the side of the dizzy, so I think it must be electronic ignition. so no condenser or points. However the coil MUST be matched.

    I've a feeling some of the problem is going to be down to it flooding, as it ain't firing.

    He could try tightening the plug gaps a thou or two under spec to ensure a proper spark gets to the mixture.
    Old skool technique for starting a car that has been stood a long time!;)

    It took me ages to figure it out. A gentleman I connected with on a Facebook group suggested it could be the coil. I then found a YouTube video on how to check a coil with voltmeter. Sure enough it was bad. $30 later I was back on the road.

    They don't handle wet plugs very well.

    As it was running fine before you removed the dizzy then it isn't the 4.2 heads.

    After sustained cranking have you pulled the plugs & are they wet or dry?

    I'm assuming you've tried holding a plug against the engine & checking that you have a good spark when cranking?
    And that if you hold the lead from the coil to the dizzy close to the block - 6mm or so - there is a good strong spark jumping the gap?

    Is it possible a connection in the wiring has been damaged, incl breaks within a wire - especially at plugs & sockets where you have fitted new items or disturbed connectors?
    Try getting someone to crank whilst you wiggle the connectors.

    My workshop manual covers testing the ignition system - about 4 pages worth.
    I think you will have the Lucas 35DLM8 distributor.
    There are online copies of the manual which were very good but they now usually rapidly disappear under a load of pop-ups & general garbage. Several of which invite you to 'Download pdf'. I've never tried clicking on the 'Download pdf' boxes so have no idea what sort of computery problems you might get if you do!

    It's here, but be careful what you click on - 'NEXT PAGE' and 'PREV PAGE' will take you from one page to the next & you'll need to view all pages for all the checks. The grey slide bar at the bottom just above 'next page' and 'prev page' will scroll you across each page so you can see all that's there.

    The E type never moves without a spare coil, condenser and points in the boot and the tools to fit them.;)

    Yes - providing no electrical or fuelling faults stopping a good spark or fuel delivery.

    The TDC mark on the crank pulley should also be more-or-less lined up with the pointer.

    The timing at that point should allow it to run & fine tuning can be done later.
