Hi,

I attached a pic below of the under hood fuse/relay box and highlighted the fuel pump relay. It is on the left side of the vehicle in the fuse/relay box. Is it possible for you to take a pic of what you are seeing so I can better help?

Let me know.

Under the dash, right side of steering column. I attached a picture of the wiring schematic for the rear lights. Fuse #9 seems to be the one you need.

Hi,

If it is clicking, that indicates there is a short and it is clicking off. What is it powering? I looked a pic of the fuse box and it doesn't show any circuit breakers other than for the power windows. If you look at pics 2 and 3, it shows the entire power distribution schematic. There See the attached pic. Is it possible for you to take a pic of it and upload it for me to see?

Let me know.

Hi,

This post was in my follow up list. That normally indicates that you would have sent a message or tried to contact me here. However, there is nothing new here. Did you try to attach something that didn't come through?

Hi,

I need you to take a pic of it and upload it for me to see. The fuel pump relay is in the fuse/relay box under the hood, so I'm not sure what you are referring to.

Let me know.

Hi,

Yep, that is an aftermarket part. That's why it wasn't making sense to me. To answer your question, it certainly could be a breaker for the electric brakes. This type is often used for that purpose.

Have you checked to see if there is spark and fuel to the engine? You indicated it won't fire to start. Do you mean there is no ignition spark? Let me know that first. Also, here is a link you may find helpful.
