Engine Compression
Unplug distributor and ignition coil. If equipped, unplug cold start injector connector, solenoid resistor, and fuel injector connectors. Check compression pressure with engine operating at normal temperature and specified cranking speed, all spark plugs removed (on dual plugs, remove exhaust side only), and throttle wide open.
