If mine misbehaves and fails to start it's aways down to the iffy connectons on top of the coil. But first ask yourself is it the lack of fuel or a spark at the plugs.

So many question need to be answered mate, how did it come about? Was it running fine before? Has anything changed? How competent are you, can you test components? Is there fuel getting to injectors? Is there a spark? Is dizzy/rotor arm/cap genuine Lucas or ****e copy? The copy's can be no good before you start! Need more info really that's all, doesn't have to be an essay just bullet point the facts and I'll try to help at least.
Hello Aquiesce
Thank you for the offer of assistance
It had been running well, with the only noticeable problem being a 'lumpy' idle on occasion. It would idle at around 400 rpm, then cut out, when hot or cold. Once restarted, it would be perfect.
The starting prob occurred last Friday - it had been a very wet week, so I figured on moisture somewhere in the ignition being most culpable. There is fuel at the injectors, and also a spark, which doesn't look too great to me.
All components replaced so far are genuine.
Cheers

Are you planning to evapourate into the ether like a spent flatus, upon successful resolution of your problem?

How old , early v8's wont start with low oil pressure , also cut out if oil pressure is too low , like SD1 v8's of BL .

There's fuel at the injectors...but are they injecting? If they arent and you have spark it could be the little inline resistor in the wiring to from the coil to the ecu. If this is disconnected then the ecu doesn't get the signal from the dizzy telling it to inject.

You mention that the spark seems weak? Do you have access to the required test parameters/equipment to test the coil? Also have you changed HT leads? If so try swapping the new King Lead with the old one, its been known to get a duff lead in a new set you know. Is there any sort of smell of fuel/flooding when you are turning it over for a prolonged period of time? Also where in the country are you?
