Fuel pump relay in 1988 K5 Blazer
 
Does anyone know where the fuel pump relay is on a 1988 K5 Blazer? Thanks
Chris

On my 89 Suburban it is on the passenger side firewall. Probably the same for yours.

You were right. Thanks. I replaced the relay and still no gas. My owners manual does not list a fuse for the fuel pump but a friend said there was an inline fuse. Do you know anything about an inline fuse on this truck?

Thanks
Chris

I don't know about a fuse. When you turn the key can you hear the pump start up? Don't start the engine, just turn it to the on position and listen around the gas tank.

No sound at all when you turn the key. Looks like I'll be dropping the gas tank. I sure wish they hadn't moved the fuel pump from an easy to get at place to the gas tank.

Thanks

The fuse on my 94 is right next to the fuel
pump relay, Its kind of encased in a plastic housing,
but might be different than yours.

The fuse for the fule pump is the "ECM B" fuse in my 87 K30 (same basic wiring). It's a 10 amp fuse.
