Routine 201 - Cranks Normally But Won't Start
NOTE:
Extended cranking due to a "NO START" condition, can load exhaust system with raw fuel. This can ruin the catalytic converter after engine is started. After a "NO START" condition has been repaired, disconnect the thermactor air supply, run the engine until surplus fuel is used up and reconnect the thermactor air supply.
