Where is the fuel pump relay on a 1996 Chevy Blazer?
The fuel pump relay on a 1996 Chevy Blazer is typically located in the engine-compartment fuse/relay center on the driver's side of the engine bay, inside the main fuse block and labeled FUEL PUMP. If it isn’t there, some configurations place the relay in the interior fuse panel behind the glove box.
Engine-bay location
The standard setup for many 1990s GM trucks, including the Blazer, uses a rectangular under-hood fuse/relay center mounted in the engine compartment. The FUEL PUMP relay is one of the relays in this block, and the cover diagram usually identifies its exact position.
Here's a quick checklist to locate the relay.
- Open the hood and locate the rectangular under-hood fuse/relay center on the driver's side of the engine bay, near the firewall or inner fender.
- Remove the relay box cover and read the label or diagram to identify the FUEL PUMP relay. It may be labeled FUEL PUMP, FUEL, or PUMP.
- Note the relay position (often a numbered slot) for easy replacement if needed.
- If you don’t see a FUEL PUMP label in the engine bay box, check the interior fuse panel behind the glove box for a spare relay of the same type labeled FUEL PUMP.
In practice, early- to mid-1990s GM trucks commonly place the fuel pump relay in the engine compartment fuse box; some late configurations place it in the interior fuse panel behind the glove box. Always check both locations and verify with the diagram on the fuse box cover.
Diagnosing a faulty fuel pump relay
When the Blazer has no start, stalls, or intermittent fuel delivery, the relay can be a prime suspect. Use these steps to test and confirm the relay's function.
- Ensure the ignition is off, then swap the FUEL PUMP relay with another identical GM relay in the same block to see if the symptom moves with the relay.
- With the ignition in Run, check for voltage at the fuel pump connector. A test light or voltmeter should show power when the relay is energized.
- Inspect the relay socket and pins for corrosion, burning, or loose connections; reseat or clean as needed.
- If swapping and testing the circuit indicate the relay is faulty, replace it with a new, correctly rated GM relay.
- If the relay tests good but the pump still doesn't run, inspect fuses, wiring to the pump, and the pump itself for other faults.
The relay is just one possible cause of fuel delivery issues; persistent problems may require further diagnosis of the fuel pump, wiring harness, or ECM-controlled circuits.
Summary
For a 1996 Chevy Blazer, the fuel pump relay is normally found in the engine-compartment fuse/relay center on the driver's side of the engine bay, labeled FUEL PUMP. If it isn’t there, check the interior fuse panel behind the glove box. Knowing the exact location helps you diagnose starting and fuel delivery problems quickly and safely.
