To troubleshoot a fuel pump issue, you'll need to check:
* The Fuel Pump Relay: This is the most likely culprit. Its location varies slightly depending on the exact model year and options of your 89 Corvette. Consult your owner's manual or a wiring diagram for the precise location. It's usually in a fuse box, often under the hood or in the passenger compartment.
* The related fuses: While there isn't a *fuel pump* fuse, there are likely fuses protecting circuits that *supply power* to the fuel pump relay. Check all fuses in the fuse box(es) – again, consult your owner's manual for proper identification. Look for fuses related to the ignition system, power distribution, and engine management. A blown fuse in one of those circuits could prevent the relay from activating.
* The wiring harness: Check the wiring leading to the fuel pump relay and the fuel pump itself for any damage, shorts, or corrosion.
In short: Don't look for a "fuel pump fuse". Look for the fuel pump relay and the fuses related to its power supply and the overall engine and ignition systems. A wiring diagram specific to your 1989 Corvette is your best resource for accurate location and identification. You can find these diagrams online through various Corvette enthusiast forums or parts websites.
