The fuel pump circuit is likely protected by a fuse in the underhood fuse box *and* may have a relay controlling its power. Simply finding a fuse labeled "fuel pump" isn't guaranteed. You might find it listed as part of a larger circuit (like an engine control circuit).
To find the correct fuse(s) and relay(s):
1. Consult your owner's manual: This is the best starting point. It should have a fuse box diagram showing the location and function of each fuse.
2. Use a wiring diagram: A wiring diagram specific to your 1988 Corvette's year and engine will show the complete circuit path for the fuel pump, revealing which fuse(s) and relay(s) are involved. You can often find these online through forums dedicated to Corvettes or automotive repair websites.
3. Check the fuse box: Carefully inspect all fuses in the underhood fuse box and the interior fuse panel (if equipped). Look for any blown fuses (usually visually apparent by a broken filament).
4. Check the fuel pump relay: Locate the relay(s) in the fuse box. They are usually square or rectangular components that you can visually inspect and sometimes swap with a known good relay to test for fault.
Important Note: Working with automotive electrical systems can be dangerous. If you're not comfortable working with car electrical systems, it's best to take your Corvette to a qualified mechanic. Incorrectly working with the fuel system can be hazardous.
