Fuel pump relay location?

Where is the location of the fuel pump relay in a 2003 nissan altima. 4 cylinder?

Where is the fuel pump relay switch located on the car listed above GXE model?

Recently I had problems starting. Determined that it was a fuel issue. Replaced the fuel pump, fuel pump relay, fuel filter and checked the lines for clogs or holes. I also checked the fuses. After all that the car started up great and ran for about a week before it happened again. I just replaced the fuel pump relay this afternoon and it started right up. About four hours later it will not start again. However i'm going to replace it one more time to ensure that this is the issue.

My question is why would this be happening? What else can I do to fix this?

Thank you in advance

Yes, while doing so I replaced the plugs with plantinums and new plug wires and rotor cap. The spark was ok but was a little weak but is now strong. As far as testing the pressure I was under the impression that the car has to be running to do so which is impossible, I guess if a new relay fixes it temporarily I can test the pressure.

Thanks, anyone else?

Hey buddy if youre still banging your head against the wall and have this issues still stop for a second and read my post, sound exactly like what I had, reason for start sometime and not other is that the wire moves and it might, its made of copper strand wire and maybe 90% of them are broken already, and not enough resistance, the the car might move when you kick it or throw hammer at it and then it will start up, anywasy no more stalling, no pun intended, read on.
Try this, get some starting fluid, spray above filter in airbox, if it starts like normal and then stalls again they you definitely have the below issues, it affects altimas from 93 to 2002.
Hi, I have had a similar issue, took the car to a shop they replaced a bunch of parts that they said were definitely bad, but thats another story, they gave me a BS story each time they replaced something, and I am talking a reputible shop in town here, not some joe shmo, found the issue myself after doing some thinking, if you cannot start car, have someone else turn key for you and you listen from backseat with the larger half of the seat folded forward, the fuel pump is right below where the velcro connects the trunk carpet right below there, but to get to it back seat comes out, along with the round pressed metal surround under the plastic pieces there along with them. Anyways listen for the fuel pump as the other person turns key, you cant do this test yourself. If you hear nothing, its most likely it, try a few times, then get out and rock the car back and forth a couple times from side to side, at this point the wire which is half broken inside may align itself, try listening again, if you are able to start car, then get the sending unit or fuel pump harness kit, forget which it was, but the wire that is bad is the one that connects to top of the fuel tank seal and the other side to the fuel pump. I hope this saves a lot of headaches for everyone, and I can't believe that nissan doesnt even have this documented. Definite design flw, basically what happens is while driving the sending unit along with fuel pump are suspended by 2 fuel lines and this wire harness, and it, just like any piece of metal eventually partially breaks when folded back and forth a thousand times.I dont believe you can buy the cable itself, it comes as a part of the kit or sending unit, one connector is flat, other square with rounded corners, I believe around 80$ bucks at nissan dealer only. Good luck, let me know how it works out.

I have a 1996 Nissan Altima GXE the relay to the Fuel Pump is not working what should I check for?

Could you please tell me where the fuel relay switch is located on a 1995 nissan Altima. I have been trying to find it to reset it for days. After I changed the fuel line on my car the car is not running right it will start and idle until the gas runs out but will not take gas when the gas peddle is used. It was running fine until I change the cracked hose. People are telling me I need to reset the fuel relay switch but I have no idea where it is.
