Chart 4-Cranks Normally But Won't Start

NOTE: Extended cranking, due to no-start condition, can load the exhaust system with raw fuel, which can ruin the catalytic converter after the engine is started. After servicing no-start condition, disconnect the thermactor air supply, operate engine until surplus fuel is used up, and then reconnect the thermactor air supply.
