To find the relay and fuses you will need to consult your owner's manual. The location of the under-hood fuse box and the interior fuse panel (if equipped) will vary slightly depending on the trim level and options, but the manual will have diagrams showing exactly where each fuse and relay is.
To troubleshoot, start by checking the:
* Fuel pump relay: This is typically in the under-hood fuse box. You'll need to find the relay diagram in your manual to identify which one is it (it will be clearly labeled on the relay itself or in the diagram). You can swap it with a known good relay of the same amperage as a test.
* Ignition fuse: Again, consult your owner's manual. This fuse provides power to the ignition system, which in turn sends power to the fuel pump relay.
If you can't find the information in your owner's manual, a quick online search for "1996 Oldsmobile 88 fuse box diagram" might turn up helpful diagrams from various sources. Remember to always disconnect the negative battery terminal before working on any electrical components.
