Hi,

Where is the fuel pump relay on this car?
I would like to swap it with another relay to see if it is bad.
Is there another relay that I can swap it out with?
Thank you for your assistance.

Hello,

The fuel pump relay is located in the fuse box under the hood (see diagram below).
First check the relay for any corrosion or burnt pin(s).
You can also test the relay.
Here is a helpful guide:

Are you having an issue with inoperative fuel pump?

Let me know of any questions.
Thank you.

Hi, thanks for the reply.
I will check into the relay first.
But yes, I am having starting problems.
car ran fine, tried to start it yesterday, seems like it wants to turn over, but doesn't.
Has gas, gauge works too.
It did this once before a few years ago, but the next day it started fine and was running fine until yesterday.
Thank you in advance for any advice you can provide...

Would I be safe to assume the fuel pump relay can be swapped out with the A/C clutch or the horn relays?

As long they have the same pin arrangement and has the same value stamped on the base, yes.

Also can you hear the fuel pump come on?
