LOCATION: In the engine compartment relay box.




2. INSPECT EFI MAIN RELAY CONTINUITY
a. Using an ohmmeter, check that there is continuity between terminals 86 and 85.
If there is no continuity, replace the relay.
b. Check that there is no continuity between terminals 87 and 30.
If there is continuity, replace the relay.




3. INSPECT EFI MAIN RELAY OPERATION
a. Apply battery positive voltage across terminals 86 and 85.
b. Using an ohmmeter, check that there is continuity between terminals 87 and 30.
If operation is not as specified, replace the relay.
