• The injection timingadvances whenthetimer isON, while itretards whenthetimer isOFF.
• When theengine stallsorthe ignition switchisin the START position, thesolenoid timerisset to

DESCRIPTION
Solenoid timer

The solenoid timerswitches onand offinaccordance witha
signal fromtheECM. Thistimer operation changesthepres-
sure inthe injection pump,thereby controlling thefuel injection
timing.
