No Spark at plugs

[chezzer85]

I was driving along when my five cut out, I've not spark at my king lead, but no spark at the plugs. Any ideas? TDC sensor?

Thanks

I'd say dizzy if there's no spark mate. Take the cap off and check if it's got moisture in it. Quite a common fault

Got spark at king lead or no spark at king lead? Could be dizzy cap/rotor arm knackered as contacts wear in cheap replacements unlike oe Ducillier ones. Dizzy should have plastic disc/seal in to prevent moisture, if no spark at king lead then possible faulty coil unit.

Sorry I meant to say I,ve got spark at king lead but not at plugs. The dissy cap and rotor arm where replaced a couple of months back. Plastic seal is in place and after a clean of the dissy cap and rotor arm, still no joy.

Possibly could be broken engine earth strap

Have you checked the new cap and rotor just incse they have failed?

I'll put the old ones back on and if that doesn't work. Check the earths.

Still not resolved this issues, need to get back out boosting.
I,ve checked all earths still no spark at the plugs. The king lead if sparking strongly however.
Can't understand it.
Any ideas?

I have changed the dissy cap, rotor arm and leads, and still no joy

Ok, have you taken each plug out in turn touching on engine and cranked over to check each is sparking? Sounds like a bad connection or spark could be too weak. Are the plugs gapped correctly? Could be coil or TDC sensor.
