The fuel pump relay location on a 1996 GMC Suburban is
in the underhood fuse block, also known as the Power Distribution Center (PDC). It's not always clearly labeled, so you'll need to consult your owner's manual or a wiring diagram. The diagram will show the relay's location within the PDC and its specific function.
Important Note: Without a diagram, pinpointing the exact relay can be tricky as the PDC contains many relays and fuses. Incorrectly identifying and replacing a relay could cause further damage. Referencing your owner's manual is strongly advised.
