Engine Compression
- Warm engine to normal operating temperature. Remove all spark plugs. On Navajo, use remote starter switch to crank engine (DO NOT crank engine with ignition switch). On B4000, disconnect ignition coil primary wire connector.
- On all models, hold throttle plate fully open. Crank engine, and note compression pressure.
