Make sure to check the fuses as well. A blown fuse might be preventing power to the relay. If all else fails, consider replacing the relay entirely; they can wear out over time.

Replacing it is a good idea. How much does a new relay usually cost?

24

You can usually find them for around $10 to $30 depending on where you shop. Not too expensive for peace of mind!

25

That’s reasonable! Is there a chance the fuel pump itself could be the issue?

26

Absolutely! If the relay and wiring check out, the fuel pump might be the culprit. Listen for it when you turn the key; if you don’t hear it, it could be time for a pump replacement.

Hey everyone! I’m trying to locate the fuel pump relay on my '91 S10. Can anyone help?

The fuel pump relay is usually located under the dash, to the left of the steering column. Check the relay box. You might also want to check the owner’s manual for specifics.

I just replaced mine last month! You’ll need a 10mm socket to remove the panel underneath the steering wheel. It’s a bit cramped, but totally doable!

32

Great tip! I’ll make sure to grab that. What replacement relay do you recommend?

While we’re at it, does anyone have a guide for the process? I’m a bit nervous about the installation.

It’s simple! Start by disconnecting the battery, then locate and remove the old relay, and just plug in the new one. Follow that by reconnecting the battery.
