I spoke to soon

today not starting, got fuel, got spark,, cant be timing as it ran before albeit roughly, but would start up straight away, now won't even offer to fire or pop/bang etc

Don't know if spark can be weak? possible ignition amplifier/ coil pack??

I'm thinking all sorts of probably stupid things now,,, e.g. theres a small drip/leak of fuel at suction side of fuel pump, could pump draw in air while ignitions on?? or is that just a stupid thought??

also firing order,, is cylinder 1 the one closest to cam pulley?





EDIT;

double checked plug leads etc all seem ok and correct order, took plug one out of head (closest to cam pulley) got one bright spark then nothing then a weak spark,,, could the coil pack be degraded on inside? do coil packs either produce weak/intermittent spark or nothing at all if broken,, or can be either or?
