Was attempting first fire today and it's not having it. The engine turns over and I can smell petrol so it IS getting to the front of the engine. I smelt the pipes and there is a smell of fuel on the N/S pipe/bank, but not the O/S.
Aside from that, it just won't fire. Not even a hint of spark or the slightest of farts. It does however spin freely 2 or so cycles, then slow/labour, then spin then slow, etc.

The dizzy, as far as I can see it (I tippexed it for orientation) is the right way round. Will double check the leads, again. I did this twice whilst reassembling engine ancillaries.

What am I missing?

Any ideas chaps?

I will go out and turn her over and record it and hopefully it will reveal something that someone will recognise.

Thanks in advance

Could it be a duff battery from that description - if it is struggling to turn it over for seconds at a time, then it may not have enough juice to spark as well.

Attach some good quality jump leads from your well charged daily driver, start its engine and try again.

Did you check for a spark?
Spins over fast enough thumbup

Strangely enough I've not done that before. Remove a HT lead and hold it to the block? confused

You said not a hint of spark.

Are your plugs getting wet yet.

Have you had the distributor out ? If so is the rotor arm pointing to the lead on the distributor cap that goes to number 1 cylinder when at the top the compression stroke. Might sound daft but I know of several people who have done this wrong (not me).

Spare plug in a lead and rest it on a rocker cover to see if there's spark would be my first thing, then check that the firing order is correct. I'd then use the connector and bulb out of the side indicator repeater in the wing and plug it into the injector loom to see if the injectors were firing. Fuel lines are on the correct way around aren't they? I'd check the engine had a good earth too, rocker cover to chassis with a multimeter.. one of those should point you in the directon of the problem smile

Yes. Did that when I put the dizzy back in. Going double check, again, the HT leads in the morning.

Don't have a multimeter. But will check the other things in the morning. Whip the plugs out first. Then check leads, etc.
Seems funny there was only a fuel smell from ONLY the N/S exhaust pipe....

One other thing - my battery was out of the car for 2 years. It was only 3 months old and a Bosch S4. Could it have discharged itself and become useless in that period?

'Ignition leads in wrong order'

Does indeed given it's one pipe from the collector to the silencer... damned clever these hydrocarbons; know their left from right
