The pump will not run until the engine is being cranked. I jumpered the relay, the pump turns on, wohooooo. Noise or leaking from the fuel tank is a sure sign of a bad pump. They also said because of the low fuel pressure that both of the front converters were damaged and were now failing.
Don't quote me on that but if you have a wiring diagram of any kind, you'll be able to tell what wire is which. The ignition switch can be off for this test. I would find it satisfactory if Nissan redesigned and fixed all vehicles by separating circuits with critical engine components from non-critical components. I was driving down the highway doing 75 in my 2004 Titan. The contact feels the fuel pump is causing the failure, not the fuel sending unit.
The vehicle was pulled over and shut off. If you have an arm reat in the middle of the rear seat, you'll need to go in through the trunk. The fuel pump had better not run with just the ignition switch turned on. The test for 12 volts is much more valid if it is done with the pump plugged in and you back-probe the wires through the rubber seal in the connector. In some cases the entire engine had to be replaced when the catalytic exploded upon the raw fuel from the misfire reaching the converter. Next, remove the fuel pump relay from that box and check for voltage on the terminals in the socket. Most Nissan Titan Fuel Pumps are installed in your fuel tank; being as liquid fuel isn't combustible, this is the best area for installation.

Nissan titan fuel pump problems requiring it to be replaced can be fixed by lifting the vehicle, and performing the necessary work underneath the truck. Section B, pages ec-423 thru 427. You won't get enough current through corrosion or carbon-tracking to run a test light or the pump, so those will give a more accurate indication if the circuit is okay.
I took it to another Nissan dealer and was told the fuel pump was only putting out 34 psi at idle and should be 60. I am in need of a newfuel pump and scared to drive my car and its leaking. My Nissan dealership states that it is due to a faulty fuel sending unit and fuel tank. If you only have a digital voltmeter, you either have to place it so you can see it from inside the vehicle, or you need a helper to crank the engine. The pump should only run for one or two seconds after you turn on the ignition switch to insure pressure is up for starting. Once the pressure build up it stops leaking that why I could never see the fuel leaking, until one morning I cranked up with the hood up. If that doesn't work, remove that relay again and do a continuity test on the remaining two terminals, not the two that had 12 volts.
Any thoughts, ideas would be greatly appreciated!!!! Read this guide on testing relays, it will help See the diagram below for the relay wiring My fuel pump went bad left me on the side of the interstate. Not sure on where to get a write-up but if you have a multimeter, you're golden. They too stated they had problems with the 04 fuel pumps. What does this relay do?

The contact stated that the fuel sending unit failed and was causing inaccurate fuel level readings. Well i found what was causing my engine control fuse to blow. From idle to wot max rpm the flow amount per mintue changes 60 times. They too stated they had problems with the 04 fuel pumps.
The manufacturer was notified and the contact was awaiting a response. It has suddenly stopped running completely. If you need further assistance you can always ask me. All vehicles use to have the engine speed controlled via mechanical linkage or cables for the gas pedal. I took it to a Nissan dealer and was told that a low speed misfire was the only code in the memory and they felt the problem with the rpm was the fuel pump as they had already replaced two 04 Titan fuel pumps. There should be 2 terminals in the socket that light the test light.
Additionally major problems with driver side door refusing to open from both the inside and outside. Rein … stall fuel pump fuse after servicing fuel system Source: Nissan Sentra Factory Service Manual The fuel pump is located under the rear seat, in the middle. A pickup truck, or any automobile for that matter, requires a working fuel pump for its engine to run efficiently. One of these goes to the pump and would be a dimmer light than the other, which is the relay coil ground signal from the computer. Dealer has realigned door numerous times but problem continues.
But, I did some research online and I'm not the first individual with this problem; on one incident a truck, same model different year, shut off on the freeway while driving at a speed were this could cause an accident.
