Do you have spark at the leads?
If so - are the ignition leads in the correct order at the dizzy? (These head-mounted dizzys have tricked a lot of folks with their weird order of connecting the leads).
If not -
Do you have juice at the coil? If yes, check the coil resistances. If not.... find out why.
What is the condition of your RPM sensor? (At the back of the engine above the flywheel. If you'd had a heater hose burst, it may have helped the plastic sheath over the sensor to fail and short circuit the signal wires from the sensor. This will still show code 1-1-1). As you suggest, this is a possibility for a point of failure if you're not seeing spark.
What is the condition / age of your igniter? (AKA power stage, found in the area of the LHF headlight). If you have a spare, swap it over. If not, check the contacts in the plug and the igniter pins for corrosion.
Once you've checked all that out, it'll be time to go though the No Fuel Scenarios.
