HELP........ it won't start
Can hear fuel pump working, checked pipe coming out of filter into metering head - fuel coming through. Plugs look wet after trying to turn it over - so fuel supply seems OK.
Get a spark coming from King lead into dizzy, but spark looks weak from the HT leads - looks yellow rather than blue and small spark? Dizzy was replaced earlier this year and appears to be OK - tried new cap and rotor. All that leaves is the LT wires from dizzy to coil to igntion module… Going to check these tommorow with multimeter.
Would grateful for any advice on this one as getting to the point where my heads going to start banging on a nearby wall :evil: . Has anyone had problems with LT wires?

Coils can give spark and break down on load with the spark dropping away. Wipe out the cap and cheak for moisture. Check for burning on the rotor arm and the contacts in the cap - clean with fine paper if necc. Also check the condition of the grahite plunger that is in the cap and goes onto the rotor arm

King lead spark is stronger, but doesn't look as good as should be. Is it possible the spark is weak and being disappated as it moves along the HTs? Got a spare coil to try tommorow - a friend said coils can get damaged if igntion accidentally left on? Was working on it yesterday, but don't recall leaving ignition on?
Does anyone know what to test when looking at the LT dizzy leads with a multimeter and what current/ampage should be present? Haynes Ignition section a bit brief and cobbled together from the all the various models. Mines a 1981 1600 with pointsless /electronic ignition.

My money is that the mixture is weak due to air leakage, I've had this problem many times. Increasing the co mixture by turning the screw clockwise may make the engine fire up.

HT leads to the plugs (and of course plugs)
As crazyquiff said, check these. I have had two cars fail to start because of these. Especially in the damp.
Would add rotor arm, dizzy cap but you say you have already.
Was working on it yesterday
What were you doing? any clues there?

So have now checked..
HT Leads
Rotor Arm
Dizzy Cap
Spark Plugs
Ignition Module
Ignition Coil
Fuel Filter
CO Adjustment
Air and Fuel Pipes
Alternator and Starter connections
Running fine Sunday - just spun on starter when tried to start on Monday Morning? Really can't get my head round this one… can't think what else to try? Missed several days of work trying to sort this :evil:
Anyone got any other ideas - thanks…
