SYSTEM RELAY CHECK 5.14<br />
GENERAL<br />
System Relay<br />
See Figure 5-28. With ignition switch turned to IGNITION and<br />
the engine stop/run switch at RUN, the ECM energizes the<br />
system relay to complete the circuit to the in-tank fuel pump,<br />
ignition coil and fuel injectors. They will remain powered as<br />
long as the engine is cranking or running, and the ECM is<br />
receiving ignition reference pul<strong>se</strong>s from the CKP. If there are<br />
no reference pul<strong>se</strong>s, the ECM will de-energize the system<br />
relay within 2 <strong>se</strong>conds after ignition is ON or engine has<br />
stalled, or immediately after the ignition is shut OFF.<br />
