I can't believe it, (said in a Victor meldrew voice)!
Newly built engine, running well, 150 miles trouble free.
Wanted to use it yesterday and it wouldn't start, a few minor phuts and a lot of starter whirring.
The spark is very weak and small, not a nice crack as you would expect.
I tried one of those spark testers, the ones that look a bit like a plug but with a much wider gap to test the strength of the spark and there is no spark on that off the plug leads.
I then but the tester on the king lead and it sparks well, result I thought!
so I changed;
The king lead,
The dizzy cap,
The rotor arm,
The coil,
The spark amplifier,
Remade all the connections on the coil,
Binned the dizzy plastic connecter and soldered solid connections.
Same result, no improvement
.
Very rapidly losing the will, sun shining and I need to put some miles on the clock.
Any ideas?

Your not fecking wrong at this rate!
I have a 100 mile round trip arranged workwise this afternoon and wwas very much looking forward to taking the chim.
On it's inaugural trip on Saturday after the engine fit, my wife and I took a trip to the coast for lunch, the only tool in the car, (please, no funny remarks!) was the wheel wrench and all was fine..........

Hi Pete,
the stepper should move to one end of the travel when switched off. Mine didnt reset and gave me cold starting problems. Amazingly, the AFM was to blame. Dont think that is linked to the spark though!
Just tried that spark tester on the other chim and that doesn't light up! The sparks are fairly weak I suppose??the stepper should move to one end of the travel when switched off.

I think I'll investigate the other chim as my stepper doesnt move.
Problem I think, solved.
A dam good tow start as the engine was flooded from trying to start it.
The slight missing at low rpm has now dissappeared so I put that down to the dodgy wires that were breaking away from the plastic connector.
I believe these were shorting out and prolonging the starting prodedure, (you could hear a cracking from this area as the engine was spinning over).
The strange thing is, there isn't enough power in the tiv system to spark up the tester off a plug lead!
120 mile round trip this pm and the car was running brilliantly.....happy days

One of the main reasons i upgraded to MS. Nitrous can literally blow a weak spark out..
An aftermarket ECU with coilpacks etc has got to be next on the list hasn't it Peter?

Hi Pete,I thought that the standard should be ok assuming all is well. A mate of mine has an old fashioned krypton tester that would tell you what is going on with the ignition system if you are interested? He is near Jcn 7 so could put a few miles on the car at the same time!
