Mechanical Inspection: Notes

CAUTION: Use a remote starter to crank engine during compression test; DO NOT  use ignition switch. Fuel injectors on many models are triggered by ignition switch during engine cranking. This could create a fire hazard or cause engine flooding, crankcase contamination, hydrostatic lock or lubrication to be washed from cylinder walls.
