Good day, I am having issues starting my car. I recently switched out the fuel pump and I am getting no pressure. Before I say it’s a bad fuel pump, I wanted to check the fuses. The 15a in the box under the hood is good and I would like to check the fuel pump relay, I just don’t know where it is and can’t find anything online about the 7th gen Maxima. Could you please let me know where it is located?

Thank you,

Robert

I believe the fuel pump relay is part of the IPDM as shown in the image below. I have seen the IPDM go out which will cause this issue but to be sure you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Here is how to replace the IPDM in case you need it. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
