Lamp Off During Cranking

Check fuse. If fuse is good, turn ignition on and disconnect Green wire to sending unit at connector (in front of intake manifold on Seville; near A/C compressor on all others). Ground wire from dash connector. If light comes on, replace sending unit. If light remains off, check for burned out bulb. If bulb is good, check printed circuit connector. If lamp and connector are good, remove steering column-to-bracket retaining screws, allow column to drop and ground Dark Green wire at ignition switch. If lamp lights, replace ignition switch. If lamp remains off, check continuity of Dark Green wire between printed circuit and sending unit connector. If continuity exists, replace printed circuit.
