Good afternoon.

The relay is in the fuse center. I attached a picture for you to view and they are marked.

The relay diagram I sent you shows fuel pump.

Which fuse box are you looking at?

There is no fuel pump relay only the control module. Here are the engine and fuel pump wiring diagrams so you can see how the system works.

Here is a guide so you can check for power to the pump to see if the pump is bad. Use the wiring diagrams below:

There are different locations for the fuel pump module here are all options.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken

Okay.

The 62 code is the key. You have a failed PCM and it needs to be replaced. That looks like it has set all the other codes as well.
