October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Power Circuits

Turn ignition on. Backprobe and check for battery voltage at ECM/PCM power terminals. If battery voltage is not present, check operation of MFI relay. See FUEL PUMP RELAY & MFI RELAY under RELAYS under MOTORS, RELAYS & SOLENOIDS. If relay is okay, check suspect circuit between ECM/PCM and relay. Perform repairs as necessary.
