When the engine is firing evenly, advance the throttle to 800 RPM. If oil
pressure is not indicated within thirty seconds, stop the engine and
determine the trouble. In cold weather it will take a few seconds longer to
get an oil pressure indication. To check the operation of the engine driven
fuel pump, turn OFF the electric fuel pump and check the fuel pressure. If
the engine has failed to start, refer to the Lycoming Operating Handbook
Engine Troubles and Their Remedies.
Starter manufacturers recommend that cranking periods be limited to
thirty seconds with a two minute rest between cranking periods. Longer
cranking periods will shorten the life of the starter.
