Has TuBy not got a test plug you could use and trigger with Tech2 to verify DIS pack and leads?

HT leads are new, dis is in perfect condition too. One test would be to swap 1 & 4 then nick his tech 2 and do the injector tests. See if fault moves :)

Guess could just attach plug to lead and stand back, would want fatty around for the test though  :o

..but if it was fuelling with no spark the plug would have been soaking wet.

I'd make sure there are pulses at the injector when cranking, and replace the injector to see if that helps. I have a load of spares here if you need a few.

Confused.....i am  ;D

Smell of eggs from exhuast ...... suggests unburnt fuel in the cat.....which suggest the plug aint firing.

Bone dry plug suggests plug is firing but no fuel getting in....

So which is it peeps   :-\

Or could it be an exhaust valve fubared.....so it is fuelling but firing unburnt fuel down the exhaust and it is firing as well.....so explains the dry plug...

I guess a compression test would prove a knackered valve  :-\

The question in my mind is how long after running was the plug checked? Had it dried out, perhaps?

Taken out first time, not run in over a week. As MotherT reported it broken, I came back to fix. New HT lead + plug, still same.

I swapped plug later again, as I ran out of brand new ones and stuck all new ones in passenger bank, again with new leads.

Don't recall inspecting the plug when I did that  :-[

So I guess when I pop back, start it. See its still same, switch off, then straight away whip the plug out?

Need to anyway for a compression test.
