Eclipse 2.0L Non-Turbo

Remove MFI (ASD) relay. Check resistance between relay terminals No. 4 and 6. Resistance should be 35-75 ohms. Connect jumper wire between battery positive terminal and relay terminal No. 6. Connect second jumper wire between battery negative terminal and MFI relay terminal No. 4. With relay energized, continuity should exist between terminals No. 2 and 8. With power source removed, continuity should not exist between terminals No. 2 and 8. If relay does not test as specified, replace MFI relay.
